High-Performance AVS2 Series 650CFM Carburetor The iFJF 1906 4-Barrel Carburetor brings legendary AVS2 performance technology to your engine build. Featuring the advanced annular flow booster design, this 650 CFM carburetor delivers exceptional fuel atomization for crisp throttle response and consistent power delivery. Whether you're upgrading a street cruiser, building a restomod, or preparing for weekend track days, the AVS2 platform provides the tunability and reliability that performance enthusiasts demand. The satin finish adds a premium look that complements any engine bay while providing enhanced corrosion resistance. Annular Booster Technology The defining feature of the AVS2 series is the annular discharge booster ring, which positions multiple fuel discharge ports around the entire circumference of each booster venturi. This design creates a finer fuel mist than traditional single-point boosters, resulting in more complete combustion, improved fuel economy at cruising speeds, and noticeably sharper throttle response. On the dyno, annular boosters have been shown to improve mid-range torque by 5-10 lb-ft compared to equivalent down-leg booster designs on a typical 350 CID small block. Vehicle Compatibility Engine Family Displacement Typical Vehicles Chevrolet Small Block V8 305 / 327 / 350 / 383 / 400 CID Camaro, Chevelle, Nova, Corvette, C10 Truck Ford Small Block V8 289 / 302 / 351W CID Mustang, Fairlane, F-100, Bronco Mopar Small Block 318 / 340 / 360 CID Dart, Duster, Charger, Challenger AMC V8 304 / 360 / 390 CID Javelin, AMX, Jeep CJ/FSJ Pontiac V8 326 / 350 / 389 / 400 CID Firebird, GTO, Grand Prix Technical Specifications Specification Detail CFM Rating 650 Barrels 4-Barrel Mounting Pattern Square Bore (4150-style) Choke Type Electric (12V) Booster Type Annular Discharge Fuel Inlet 3/8" NPT Secondaries Vacuum-Operated (Adjustable Air Valve) Finish Satin Aluminum Part Number 1906 SKU FJ-CBRT-1906 Key Features 650 CFM airflow rating - optimized for 300-400+ HP street performance engines Annular discharge boosters for superior atomization and throttle response Electric choke with fast-idle cam for reliable cold starts Adjustable vacuum secondary air valve - tune secondary engagement without removing carburetor Two-piece cast aluminum body with satin finish Compatible with both manual and automatic transmissions Accepts standard 5-1/8" air cleaner flange Frequently Asked Questions Q: What is the CFM rating and what engines does it support?A: The iFJF 1906 is rated at 650 CFM, making it ideal for small-block V8 engines between 305 and 400 cubic inches. It is perfectly suited for 327, 350, 383, and 400 CID engines in street performance and mild racing applications. Q: What does the annular booster design do?A: The annular discharge booster design provides superior fuel atomization compared to traditional down-leg boosters. This results in improved throttle response, better fuel economy at cruise, and more consistent air-fuel mixture across all RPM ranges. Q: Does this carburetor come with an electric choke?A: Yes, the iFJF 1906 features an integrated electric choke for reliable cold starts. Simply connect to a 12V ignition-switched power source and the choke will automatically adjust based on engine temperature. Q: Is this a square bore or spread bore carburetor?A: This is a square bore (4150-style) carburetor designed to bolt directly onto square bore intake manifolds. It can also be used with spread bore manifolds using an adapter plate (sold separately). Q: What is the satin finish and why does it matter?A: The satin finish is a premium aesthetic treatment that provides a semi-gloss, non-reflective surface. It resists fuel stains and corrosion better than raw aluminum while maintaining a classic performance look that complements any engine bay. Q: Is tuning required out of the box?A: The carburetor comes with baseline calibration suitable for a typical 350 CID engine at sea level. Minor adjustments to idle mixture screws, accelerator pump, and possibly jet changes may be needed based on your specific engine combination, elevation, and performance goals. Q: What makes this different from the standard AVS series?A: The AVS2 series features the upgraded annular flow booster design, improved fuel metering circuits, and a revised air valve system that provides more precise secondary engagement compared to the original AVS design, resulting in smoother power delivery and better mid-range torque.

Our 1901R replacement addresses all these weaknesses with modern CNC machining, improved aluminum alloy, and precision calibration. You get the signature Quadrajet sound and performance without the headaches of a 50-year-old core. Each unit is wet-flow tested before leaving the factory. We stand behind every carburetor with our satisfaction guarantee. Installation Tips Verify intake manifold is square bore pattern (not spread bore without adapter) Set idle mixture screws to 2-1/2 turns out as starting point Use a phenolic spacer to reduce heat soak on hot starts Check fuel pressure — Quadrajets prefer 5-6 PSI maximum Connect choke cable to manual choke linkage before final mounting Torque mounting bolts to 12-15 ft-lbs in a crisscross pattern Frequently Asked Questions Q: Will this fit my 1969 Camaro with a 350?A: Yes. This 1901R Quadrajet 4MV is a direct replacement for 1966-1973 Chevy 327-454 engines with a square bore intake manifold. Your 1969 Camaro 350 is a perfect match. Q: Does this carburetor come with a gasket?A: Yes, a base gasket is included. We recommend using a quality fiber gasket or 1/4" phenolic spacer for best results. Q: Is this a rebuilt original or brand new?A: This is a 100% brand new carburetor — not a remanufactured or rebuilt core. No core charge, no waiting for a rebuild. Q: Do I need an adapter to install this on a spread bore manifold?A: This is a square bore carburetor. If your intake manifold is a spread bore (common on later Quadrajets), you will need a square-to-spread bore adapter plate (sold separately). Q: How do I adjust the manual choke?A: The choke lever connects to a standard choke cable (not included). Route the cable through your firewall and mount under the dash. Pull to close choke for cold starts, push to open as engine warms. Q: What's the difference between vacuum secondary and mechanical secondary?A: Vacuum secondaries open based on engine load — they only engage when the engine can actually use the extra air/fuel. This prevents bogging and improves driveability on the street compared to mechanical secondaries. Q: Does this carburetor have EGR provisions?A: No. This carburetor does not include EGR provisions, making it ideal for non-emissions applications, off-road use, or vehicles with EGR deleted.

Our 1901R gives you the legendary Quadrajet design with modern manufacturing: precision CNC-machined metering circuits, properly sealed well plugs, and a brand new casting that hasn't been through 50 years of heat cycling. The result is a carburetor that starts easier, idles smoother, and delivers the fuel economy these trucks were known for when new. Frequently Asked Questions Q: Will this fit my 1970 C10 with a 350?A: Yes, this is a direct replacement for your 1970 C10 350. The 1901R bolts to the factory Quadrajet intake manifold and uses the same throttle linkage and fuel line connection. Q: Do I need to change my intake manifold?A: No. The 1901R fits the factory cast iron Quadrajet intake manifold found on 1968-1973 GM trucks. No adapter needed. Q: How do I connect the throttle linkage?A: The throttle lever accepts the factory GM throttle cable and transmission kickdown cable (TH350/TH400). The geometry matches OEM specifications. Q: Is this carburetor good for towing?A: Absolutely. The Quadrajet's small primaries provide excellent fuel economy during cruise while the massive secondaries deliver full power for towing and hauling heavy loads. Q: Can I convert this to electric choke?A: This model is manual choke only by design. If you prefer electric choke, see our other Quadrajet-style options.

Product Overview The iFJF 1901 Thunder AVS2 500 CFM carburetor is the next evolution in the Thunder carburetor lineup, featuring enhanced annular flow boosters for even finer fuel atomization. With 12V electric choke, non-EGR calibration, and a clean satin finish, this 4-barrel is purpose-built for small cubic-inch V8 and V6 engines where crisp throttle response matters more than maximum CFM. Ideal for restomods, street rods, and daily drivers with 260-327 CID engines. Key Features AVS2 Annular Boosters — Second-generation annular discharge booster design with improved fuel distribution across all 8 discharge holes. Noticeably smoother idle and better tip-in response than first-gen designs. 500 CFM Precision Calibration — Calibrated specifically for 260-327 CID small block V8s. Avoids the tuning headaches of oversized carburetors on small engines. Electric Choke — 12V automatic choke with adjustable housing. Cold starts in any weather without a manual choke cable. Non-EGR Design — No EGR port or provisions. Ideal for pre-emissions vehicles, off-road builds, and engines with EGR systems removed. Satin Finish Aluminum — Clean, understated appearance that doesn't yellow or discolor. Resists fuel staining and corrosion.

Compatibility Engine Displacement Best Match Chevy Small Block 262-327 CID Mild street cam, stock heads, dual-plane intake Ford Windsor 260-302 CID Stock to mild build, great for early Mustangs Jeep V8 304-360 CID Good for Jeep CJ/Wagoneer with square bore manifold AMC V8 290-304 CID Direct fit on square bore aftermarket intakes Specifications Parameter Value Part Number 1901 CFM Rating 500 CFM Barrel Type 4-Barrel Square Bore Choke 12V Electric Primary Jet 0.095" Secondary Jet 0.095" EGR Non-EGR Finish Satin Aluminum Why AVS2? The AVS2 upgrades the classic Thunder/Edelbrock design with annular flow boosters — the same technology used in high-end racing carburetors. Instead of a single fuel discharge point, each booster has 8 precision-drilled holes that create a cone-shaped fuel mist. The result is more complete combustion at part throttle, smoother transitions, and fuel atomization that rivals EFI at a fraction of the cost. Frequently Asked Questions Q: What's the difference between AVS and AVS2?A: The AVS2 uses annular discharge boosters (8-hole ring) instead of standard down-leg boosters, providing finer fuel atomization. This results in smoother idle, better throttle response, and improved part-throttle fuel economy. Q: Does non-EGR mean I can't use it on a street car?A: Non-EGR simply means the carburetor does not have exhaust gas recirculation ports. It works perfectly on street cars — especially pre-1975 vehicles that didn't have EGR or vehicles where EGR has been removed for off-road use. Q: Can I use this on a 350 Chevy?A: A 500 CFM carburetor may be slightly restrictive for a built 350 at high RPM. For stock or mild 350s, it will work but may limit top-end power. For performance 350+ builds, consider our 600-650 CFM options. Q: Does this come with a fuel line and filter?A: A 5/8"-20 inlet fitting is included. The fuel line and inline filter are sold separately — we recommend a 3/8" braided line with serviceable filter. Q: How do I set the idle mixture?A: Start both mixture screws at 2 turns out. With engine warm and choke fully open, turn each screw in slowly until RPM drops, then back out 1/2 turn. Adjust idle speed to 700-800 RPM.

The factory Solex 34 PICT-3 carburetor was adequate when new but is now notorious for warped throttle bodies, clogged idle circuits, and difficult cold starts. The Weber IDF design has been the gold standard for air-cooled VW performance since the 1970s. It offers superior tunability with replaceable jets, a more robust accelerator pump circuit, and dramatically improved throttle response. Whether you're restoring a daily driver or building a weekend cruiser, this carburetor transforms how your vintage VW drives. Installation Tips Use new paper gaskets on both sides of the phenolic spacer block Set idle mixture screws at 1 turn out from seated as starting point Verify fuel pressure at 2.5-3.0 PSI — mechanical pumps may need a regulator Base idle speed: 850-900 RPM on air-cooled engines Check for vacuum leaks at intake boots and manifold end castings before tuning With a 009 mechanical advance distributor, set timing to 28-32° BTDC at 3000+ RPM Frequently Asked Questions Q: Will this fit my 1974 Super Beetle with stock engine?A: Yes. The 18990035 Weber 44 IDF is a direct bolt-on replacement for the stock Solex carburetor on your 1974 Super Beetle 1600cc. It bolts to the factory intake manifold center section. Q: Do I need to change my distributor when installing this carburetor?A: The Weber 44 IDF works well with both vacuum-advance (SVDA) and centrifugal-advance (009) distributors. If using a 009, make sure the vacuum port on the carb is capped. Q: Is this carburetor too big for a stock 1600cc engine?A: The 44 IDF is properly sized for stock to mild 1600cc engines when properly jetted. It comes pre-calibrated for 1600cc. If upgrading to 1776cc or larger, you may want to increase main jet sizes. Q: What air filter fits on this carburetor?A: The integrated air horn accepts standard IDF-style air filter assemblies. Low-profile oval filters (commonly available for Beetle engine bays) fit perfectly. Q: Does this carburetor work with dual carb setups?A: This carburetor is designed for single center-mount applications. For dual carb setups, consider dual 40 IDF or 44 IDF kits with appropriate manifolds. Q: Will I need to re-jet for my elevation?A: At elevations above 4,000 ft, you may want to reduce main jet size by 5-10 numbers. Below 4,000 ft, the factory jetting will work well.

Enough airflow for performance without over-carbureting. Satin Finish Aluminum — Corrosion-resistant die-cast aluminum body with a clean satin appearance that stays looking good even after mud and power washing. Square Bore Pattern — Direct fit on most aftermarket intake manifolds and factory 4-barrel square bore intakes. Compatibility Application Engine Size Notes Small Block Chevy (283-400) 283-400 CID Best for 327, 350, 383, 400 with mild cam Small Block Ford (289-351W) 289-351 CID Ideal for 302 and 351W builds Mopar Small Block (318-360) 318-360 CID Fits LA and Magnum engines Mild Big Block V8 396-454 CID Suitable for stock to mild big block builds Off-Road / 4x4 Vehicles Any V8 Optimized for steep angles and rough terrain Specifications Parameter Value Part Number 18025 (also referenced as 1825) CFM Rating 650 CFM Barrels 4-Barrel Square Bore Choke Type Manual Choke Booster Type Annular Discharge Primary Jet 0.095" Secondary Jet 0.098" Body Material Die-Cast Aluminum (Satin Finish) Throttle Bore 1-11/16" Primary / 1-11/16" Secondary Why Choose iFJF Thunder AVS for Off-Road? Standard street carburetors fail off-road. Fuel slosh causes flooding on steep climbs. Vibration shakes floats out of adjustment. Dust clogs vent tubes. We designed the Thunder AVS from the ground up for the abuse of off-roading — sealed vent tubes, spring-loaded needles, and a float bowl design that keeps fuel where it belongs even at 45-degree angles. The annular boosters provide better low-end torque response, critical for crawling over obstacles at idle speed. If you've ever had your rig die mid-climb because the carb flooded out, this is the fix. Installation Notes Standard square bore flange — fits Edelbrock Performer, RPM, and most aftermarket intakes Use a 1/4" heat insulator gasket to prevent heat soak on hot engines Route manual choke cable away from exhaust manifolds/headers Set idle mixture screws at 1-1/2 turns out as baseline Fuel pressure: 5.5 PSI maximum (use regulator if mechanical pump exceeds this) Frequently Asked Questions Q: Will this carburetor work at extreme angles while rock crawling?A: Yes. The Thunder AVS is specifically designed for off-road use with spring-loaded needle and seat assemblies and optimized float levels that resist fuel slosh at angles up to 45 degrees. Q: Can I use this on a street-driven truck too?A: Absolutely. While optimized for off-road, this carburetor performs excellently on the street. The annular boosters deliver crisp throttle response for daily driving. Q: What's the difference between annular and down-leg boosters?A: Annular boosters have 8 small discharge holes arranged in a ring, providing finer fuel atomization and better low-RPM torque. Down-leg boosters have a single discharge point and are typically used in race-only applications. Q: Does this come with mounting hardware?A: Yes — mounting studs, nuts, washers, and a base gasket are included in the box. Q: What fuel line size do I need?A: The fuel inlet accepts a 5/8"-20 thread fitting. We recommend 3/8" fuel line for engines up to 400 HP. Q: Will this fit my Jeep CJ with a Chevy 350 swap?A: Yes — this is an excellent choice for a Chevy 350 swapped into a Jeep CJ, YJ, or TJ. The off-road design handles the angles you'll encounter on the trail.

The 600 CFM Performer has been the go-to street performance carburetor for decades. Our 1806 builds on that legacy with modern manufacturing precision. The air valve secondary design is inherently smoother than mechanical secondaries for street driving — you don't get the sudden "hit" that can break tires loose unexpectedly on wet pavement. Combined with the 12V electric choke, this is the set-it-and-forget-it carburetor that starts reliably and drives smoothly from cold mornings to hot summer afternoons. Frequently Asked Questions Q: Will this fit my 350 Chevy with an Edelbrock Performer intake?A: Yes. The 1806 has a standard square bore flange that matches the Edelbrock Performer, Performer RPM, and most other aftermarket intakes. Direct bolt-on — no adapter needed. Q: What's air valve secondary vs. vacuum secondary?A: Air valve secondaries use a spring-loaded flap above the secondary throttle plates. As airflow increases, the valve opens progressively — providing smoother engagement than mechanical secondaries and more precise control than pure vacuum secondaries. Q: Will this work with my TH350 automatic transmission?A: Yes. The throttle lever includes provisions for GM TH350, TH400, 700R4, and 200-4R kickdown cables. Ford AOD and C4/C6 linkages are also supported with the correct bracket. Q: Does non-EGR mean it won't pass emissions?A: Non-EGR carburetors are intended for pre-emissions vehicles (generally pre-1975), off-road vehicles, or vehicles where the EGR system has been removed. Not for use on emissions-controlled vehicles where EGR is required by law. Q: Can I use this on a marine engine?A: No. Marine engines require USCG-approved carburetors with specific safety features (sealed overflow, J-tube venting). Use only marine-rated carburetors on boats. Q: What timing should I run with this carburetor?A: For most small block Chevy engines, start with 10-12° initial timing and 34-36° total mechanical advance by 3,000 RPM. Adjust vacuum advance to provide 10-12° additional under light cruise.

Factory carburetors from the 60s-80s are now 40-60 years old. They suffer from warped castings, corroded passages, worn throttle shafts, and degraded accelerator pumps. Our 1805 is brand new — no core required, no rebuilding, no surprises. The annular boosters found on the Thunder AVS are a genuine upgrade over standard boosters, providing fuel atomization comparable to fuel injection at a fraction of the cost. Each unit is wet-flow tested and pre-calibrated for out-of-the-box performance. Frequently Asked Questions Q: Will this bolt onto a stock Chevy 350 intake manifold?A: Yes — as long as your intake manifold has a square bore flange pattern. Most 1966-and-later Chevy small block intakes are square bore. If you have a spread bore manifold (e.g., some Quadrajet applications), you'll need an adapter. Q: What's included in the box?A: Carburetor, base gasket, mounting studs/nuts/washers, and installation instructions. Q: Can I use this with an automatic transmission?A: Yes. The 1805 works with both automatic and manual transmissions. You'll need to connect your transmission's kickdown linkage (TH350/TH400/700R4) using the provided throttle lever. Q: How do I hook up the manual choke?A: Route a universal choke cable (not included) from the choke lever on the carburetor, through the firewall grommet, to a dash-mounted pull knob. Most auto parts stores carry universal choke cable kits for $10-20. Q: Will this work at high altitude (5,000+ ft)?A: At high altitude, you may need to lean the mixture. The 1805 accepts standard Edelbrock/Thunder-series jets and metering rods for calibration. For altitudes above 5,000 ft, go down 1-2 jet sizes.

Small engines don't need big carbs. A 305 with a 750 CFM carb will have sluggish throttle response, poor fuel economy, and a weak vacuum signal that makes tuning impossible. The 1801 is designed and calibrated specifically for 260-327 CID engines. You'll get crisp off-idle response, stable idle, and excellent part-throttle manners — the things you actually feel when driving. Frequently Asked Questions Q: Is 500 CFM enough for my 305 Chevy?A: Yes. A 305 at 5,500 RPM requires approximately 485 CFM at 100% volumetric efficiency. The 500 CFM rating is ideal — it provides enough airflow without the sluggish low-speed response of an oversized carb. Q: How do I wire the electric choke?A: Connect the choke's positive terminal to a 12V ignition-switched source (only powered when the key is ON). Do NOT connect to the coil positive terminal. The choke housing grounds through the carburetor body. Q: Can I adjust the choke?A: Yes. Loosen the three screws on the choke housing and rotate it to adjust the opening rate. Turn toward "rich" (clockwise) for slower opening in cold weather; toward "lean" (counterclockwise) for faster opening in warm climates. Q: Will this fit a 2-barrel to 4-barrel conversion?A: Yes, as long as you use a 4-barrel square bore intake manifold. You cannot bolt a 4-barrel carb to a 2-barrel intake without an adapter (not recommended). Q: Is this carb compatible with EGR?A: This carburetor does not have EGR provisions. It is designed for non-EGR applications or vehicles with EGR systems deleted (for off-road/racing use only).

A: Yes — 750 CFM is over-carbureted for a small block 350. For 305-350 marine engines, use the 1409 (600 CFM) instead. The 1410 is designed for big block applications 396 cubic inches and larger. Q: Can I use this on a Mercruiser 7.4L Bravo? A: Yes, the 1410 is an excellent upgrade for the Mercruiser 7.4L (454) when paired with a square bore intake manifold. Verify your intake flange type before ordering. Q: What fuel line size is needed? A: We recommend 3/8" minimum marine-rated fuel line for 750 CFM applications. For engines above 500 HP, use 1/2" fuel line with a high-volume marine fuel pump. Q: What's the expected fuel consumption at cruise? A: Fuel consumption depends on engine load, hull type, and cruise RPM. The 1410's air valve secondary design helps maintain reasonable fuel economy at part-throttle cruise because the secondary barrels only open under high demand. Q: Does this include a flame arrestor? A: A flame arrestor is not included and must be used. All marine inboard engines require a USCG-approved flame arrestor. The 1410 accepts standard 5-1/8" neck flame arrestors. 🔗 Related Products from iFJF 1409 Marine Carburetor 600 CFM 1806 Performer Carburetor 4-Barrel 📚 Helpful Installation Guides 📖 Diesel Engine Cooling System Flush Guide 📖 GM Truck Tie Rod Upgrade Installation

Edelbrock 1409 Marine Carburetor — 600 CFM, USCG Compliant The iFJF 1409 Marine Carburetor is purpose-built for the water. With 600 CFM airflow, an electric choke, and full USCG compliance, this 4-barrel carburetor is engineered for Chrysler Marine and Chevy Marine V8 engines. Unlike automotive carburetors, the 1409 features sealed throttle shafts, J-style vent tubes, and marine-specific fuel bowl vents that prevent fuel spillage in rough water conditions. Key Marine-Specific Features USCG Compliant — Meets United States Coast Guard safety requirements for fuel system integrity on inboard marine engines Sealed Throttle Shafts — Prevents fuel and vapor leakage into the engine compartment J-Style Vent Tubes — Redirects fuel bowl overflow back into the venturi instead of spilling onto the intake manifold Marine-Calibrated Jetting — Optimized fuel curve for constant-load marine operation vs stop-and-go automotive use 600 CFM Flow — Ideal for Chrysler Marine 318-440 and Chevy Marine 305-454 V8 engines Electric Choke — Reliable cold starts on the water with simple 12V wiring Gold Finish — Premium corrosion-resistant coating for the marine environment Marine Engine Compatibility Marine Engine Displacement Carburetor Model Chrysler Marine 318, 360, 400, 440 V8 Edelbrock 1409 replacement Chevy Marine 305, 350, 454 V8 Edelbrock 1409 replacement Mercruiser (OEM) 5.0L, 5.7L, 7.4L Square bore intake required OMC / Volvo Penta 5.0L, 5.7L, 7.4L, 8.1L Verify intake manifold pattern Specifications Specification Value CFM Rating 600 CFM Barrels 4-Barrel Choke Type Electric (12V) Flange Type Square Bore Finish Gold Dichromate Certification USCG Compliant Frequently Asked Questions Q: Can I use an automotive carburetor on my boat? A: No. Marine carburetors have specific safety features — sealed throttle shafts, J-vent tubes, and marine-specific calibrations — that auto carburetors lack. Using an automotive carburetor on a boat is dangerous and violates USCG regulations. Q: Will this bolt up to my Mercruiser intake? A: The 1409 has a standard square bore flange pattern. Most Mercruiser 5.0L/5.7L intake manifolds are spread bore (Quadrajet pattern). A square-to-spread bore adapter plate is required for those applications. The 7.4L/454 often uses a square bore intake and can accept the 1409 directly. Q: Do I need a different fuel line for marine use? A: Yes — marine applications require USCG Type A1 fuel hose with fire-resistant rating. Standard automotive fuel line is not approved for enclosed engine compartments on boats. Q: What fuel pressure should I run? A: 5.5-6.0 PSI maximum. A marine-grade fuel pressure regulator is recommended. High fuel pressure from a mechanical pump (common on big block marine engines) can flood the carburetor and create a fire hazard. Q: Is tuning different for marine vs automotive? A: Marine engines operate under constant load with less variation in RPM, so the fuel curve is calibrated richer at cruise. The 1409 comes pre-calibrated for marine use. Only adjust jetting if you're at high altitude or have made significant engine modifications. Q: Does installation require a marine mechanic? A: While a DIY-capable boat owner can install this carburetor, we recommend professional installation if you're unfamiliar with marine fuel systems. Improper installation creates serious fire and explosion risks in enclosed engine compartments. 🔗 Related Products from iFJF 1409 Marine Carburetor 600 CFM 1410 Marine Carburetor 750 CFM (Golden) 📚 Helpful Installation Guides 📖 Diesel Engine Cooling System Flush Guide 📖 GM Truck Tie Rod Upgrade Installation

Electric Choke: Automatic cold-start enrichment. No cable to route, no manual adjustment needed after initial setup. Wired to a 12V ignition-switched source. All-Aluminum Two-Piece Construction: Lighter than cast-iron competitors and runs cooler. Two-piece design reduces warping risk and simplifies disassembly for tuning or cleaning. No Power Valve to Blow Out: Unlike Holley-style carbs, the Edelbrock-compatible design uses metering rods instead of a power valve — engine backfire won't leave you stranded with a flooded engine. Tool-Free Rod Changes: Metering rods and springs can be swapped in seconds through the top cover — no carb removal, no draining fuel bowls. Complete Kit: Includes everything you need: carburetor, square-bore base gasket, horn gasket, air cleaner stud, 2 fuel filters, 4 clamps, fuel line, red choke positive wire, and black choke ground wire. Compatibility This 4-barrel square-bore carburetor fits square-bore intake manifolds including: Edelbrock Performer EPS Edelbrock Performer RPM Edelbrock RPM Air Gap Edelbrock Torker II Other aftermarket square-bore manifolds with the same flange pattern Important Fitment Notes NOT for computer-controlled applications — including GM vehicles with Q-Jet carburetors (1981+) and Ford vehicles with AOD transmissions (1981+). For engines with a spread-bore intake manifold, an adapter plate is required (sold separately). Recommended fuel pressure: 5.5–7 psi. Install an inline fuel pressure regulator if your mechanical pump exceeds 7 psi. Throttle linkage stud location matches Edelbrock Performer series — compatible with most GM, Ford, and Mopar throttle cable/kickdown brackets.

Unlike buying a used, worn-out Edelbrock 1406 on eBay that needs a rebuild, the iFJF 1406 arrives factory-fresh and ready to run. At $239.99 — roughly half the price of a new Edelbrock — you get the same 600 CFM performance, the same square-bore footprint, and compatible internal parts (uses Edelbrock rebuild kit #1487 if you ever need to service it later). Every unit is pressure-tested before shipping. Backed by a 30-day return policy and expert tech support. Installation Tips Fuel Pressure: Verify 5.5–7 psi at the carb inlet. Mechanical pumps on some engines (especially big-block Chevys) can spike above 9 psi — use a regulator. Choke Wiring: Connect the red wire to a 12V ignition-switched source (not coil positive). The black wire goes to a clean chassis ground. The choke housing must NOT be grounded through the carb body — use the dedicated ground wire. Initial Tune: Set idle mixture screws 1-1/2 turns out from lightly seated as a starting point. Set idle speed to 700–800 RPM (manual trans) or 650 RPM in gear (automatic). Float Level: Pre-check float level before installation. Fuel level should be 7/16" from the top of the bowl with the engine idling and the sight plug removed. Break-In: Drive the vehicle for 20–30 minutes at operating temperature. Re-check idle mixture and speed after the engine heat-soaks. Frequently Asked Questions Q: Is this a genuine Edelbrock 1406?A: No — this is an iFJF replacement carburetor engineered to match the Edelbrock 1406 in fitment, CFM rating, and performance. It is not manufactured by or affiliated with Edelbrock. However, the internal design is compatible with Edelbrock rebuild kit #1487 for future servicing. Q: What's the difference between the 1405 and 1406?A: The main difference is the choke type. The 1405 has a manual choke (you pull a cable from the cabin), while the 1406 has an electric choke that operates automatically. Both flow 600 CFM and share the same bolt pattern. Q: Will this fit my 350 Chevy / 351 Ford / 318 Mopar?A: It fits any engine with a square-bore intake manifold. If your engine currently has a spread-bore (Quadrajet-style) intake, you'll need a square-bore adapter plate. This carburetor works well on small-blocks from 305–402 cubic inches with mild to moderate cam profiles. Q: Can I use this on a marine engine?A: We do not recommend this carburetor for marine use. Marine applications require a USCG-approved carburetor with specific safety features (J-tube vents, sealed throttle shafts). Misfueling a marine engine can create a fire hazard. Q: Do I need to adjust anything out of the box?A: The carburetor is pre-calibrated for typical street engines, but you should always check float level, set idle mixture, and verify choke operation before driving. Every engine combination is different, so some fine-tuning is expected. Q: What fuel line fitting size do I need?A: The fuel inlet is threaded 5/8"-20. Most installations use a 5/8"-20 to -6AN or 3/8" inverted flare adapter (commonly included with aftermarket fuel line kits). A 3/8" fuel line is recommended for engines making up to 400 hp. Q: How does this compare to rebuilding an old Edelbrock 1406?A: A rebuild kit costs $25–$50 and takes 3–4 hours, but it doesn't fix worn throttle shaft bores, corroded castings, or stripped threads — common issues on 20+ year-old carbs. At $239.99, the iFJF 1406 gives you a brand-new casting with fresh components and zero wear. If you prefer rebuilding, check out our Edelbrock 1406/1405 Rebuild Guide. Q: What's your return policy?A: 30-day returns. If the carburetor doesn't meet your expectations, return it in resalable condition for a full refund. Please don't install it with permanent modifications (filing, drilling) unless you're sure you're keeping it.

The electric choke on the 1406 makes cold starts effortless — just pump the gas once, turn the key, and the 12V choke element handles the rest. The AFB-style metering rod system delivers consistent air/fuel ratios without the power valve failure headaches common on competing designs. Whether it's a daily-driven Silverado, a weekend Mustang, or a restomod GMC, the 1406 is the most popular street performance carburetor for a reason. Frequently Asked Questions Q: How do I wire the electric choke? A: Connect the choke's positive terminal to a 12V ignition-switched source (key-on power only). The most reliable connection point is the ignition coil positive terminal or the fuse box IGN terminal. Do NOT connect to the alternator or a constant 12V source — the choke only needs power when the engine is running. Q: Will this fit my Ford 302? A: Yes, it fits any engine with a square bore intake manifold. For Ford 302 applications, pair with a Performer or Performer RPM intake manifold. You may need a throttle bracket adapter for Ford throttle cable compatibility. Q: What's the difference between the 1405 and 1406? A: The 1405 has a manual choke (cable-operated), while the 1406 has an electric choke. Internally, the jetting and calibration are nearly identical. Choose the 1406 if you want automatic cold-start convenience; choose the 1405 if you prefer manual control or are building a race/off-road application. Q: Do I need a calibration kit? A: The 1406 comes pre-calibrated for typical street V8 applications from sea level to approximately 4,000 feet. At higher altitudes or for modified engines with aggressive cams, a metering rod/jet calibration kit is recommended. Q: What fuel pressure is required? A: The 1406 operates best at 5.5-6.0 PSI fuel pressure. Use a quality fuel pressure regulator if your mechanical or electric pump exceeds 6.5 PSI, as excessive pressure can overpower the needle and seat. Q: Is this compatible with EGR? A: No — this is a non-EGR carburetor designed for performance applications. For off-road and racing use only where emissions equipment removal is legal. 🔗 Related Products from iFJF 1405 Performer 600 CFM Carburetor (Manual Choke) 1404 Performer 500 CFM Carburetor 1478 Electric Choke Kit for 1405/1406 📚 Helpful Installation Guides 📖 Diesel Engine Cooling System Flush Guide 📖 GM Truck Tie Rod Upgrade Installation
