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.

Product Overview The iFJF 1801 Thunder AVS 500 CFM 4-barrel carburetor is purpose-calibrated for small displacement V8 and V6 engines. With annular discharge boosters, electric choke, and the signature Thunder AVS tunability, this carburetor delivers crisp throttle response and excellent driveability on engines from 260 to 327 cubic inches. Perfect for street rods, compact V8s, and mild cruiser builds. Key Features 500 CFM — Right-Sized — Properly sized for smaller displacement engines (260-327 CID). Avoids the low-speed drivability issues caused by over-carbureting with larger 600-750 CFM carbs. Electric Choke — Automatic 12V electric choke provides hassle-free cold starts. Heats up in 1-2 minutes and opens progressively — no manual cable to route. Annular Discharge Boosters — Eight-hole booster rings deliver superior fuel atomization at low airflow rates, critical for small engines that spend most of their time at part throttle. Tool-Free Secondary Tuning — Change secondary metering rods in seconds through the top of the carburetor. No disassembly required. Aluminum Body — Lightweight, corrosion-resistant, and runs cooler than cast iron. Factory pre-calibrated and wet-flow tested. Compatibility Engine Displacement Application Notes Chevy Small Block 262, 267, 283, 305, 307 Best for mild-cam street engines Ford Small Block 255, 260, 289, 302 Ideal for Mustang, Falcon, early F-100 Buick V6 / V8 231, 252, 260, 300 Fits square bore intake manifolds Chevy V6 (4.3L) 262 Requires 4-barrel intake manifold Jeep V8 304 Good match for CJ and Wagoneer builds Specifications Parameter Value Part Number 1801 CFM Rating 500 CFM Barrels 4-Barrel Square Bore Choke 12V Electric Choke Booster Type Annular Discharge Primary Jet 0.086" (factory) Secondary Jet 0.092" (factory) Body Material Die-Cast Aluminum Why 500 CFM? 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).

Edelbrock 1410 Marine Performer Carburetor — 750 CFM, 4-Barrel The iFJF 1410 Marine Carburetor delivers 750 CFM of USCG-compliant airflow for big block marine V8 engines. When 600 CFM isn't enough for your 454, 460, or 502 marine engine, the 1410's larger venturi and increased flow capacity provide the top-end power needed for heavy cruisers, performance boats, and high-output inboard applications. Key Features 750 CFM Flow — 25% more airflow than the 1409, designed for big block V8 marine engines 396-502+ cubic inches Electric Choke — Reliable 12V automatic choke for consistent cold starts on the water USCG Compliant — Sealed throttle shafts, marine vent routing, and all required safety features Air Valve Secondary — Demand-based secondary opening for smooth acceleration without bog Golden Dichromate Finish — Excellent corrosion resistance for marine environments Big Block Calibration — Factory-jetted for the fuel demands of high-displacement marine engines Ideal Applications Engine Displacement Typical Use Chevy Marine Big Block 396, 427, 454, 502 Cruisers, performance boats, ski boats Chrysler Marine Big Block 400, 413, 426, 440 Heavy cruisers, houseboats Ford Marine 429, 460 Jet boats, performance inboards Specifications Specification Value CFM Rating 750 CFM Barrels 4-Barrel Choke Type Electric (12V) Flange Type Square Bore Finish Gold Dichromate Secondary Type Air Valve (Mechanical) Certification USCG Compliant Frequently Asked Questions Q: Is 750 CFM too much for my 350? 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

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

Frequently Asked Questions Q: Should I get the 1405 or 1406 for my truck?A: For a daily-driven truck or any vehicle you want to start easily in all weather, the 1406 (electric choke) is the better choice. The 1405 (manual choke) requires installing a choke cable through the firewall and manual adjustment every cold start — better suited to dedicated race/off-road vehicles. Q: Where do I connect the electric choke wire?A: Connect to a 12V ignition-switched source — typically the ignition coil positive terminal, an IGN terminal on the fuse block, or the alternator field wire. DO NOT connect to the coil negative or to a constant 12V source (will drain battery). Q: Will this fit my Quadrajet intake?A: Quadrajet (spread bore) intakes require a square bore to spread bore adapter plate. Alternatively, consider an aftermarket dual-plane square bore intake manifold for best results. Q: Does this carb work at high altitude?A: The 1406 runs slightly rich at altitude. Above 5,000 feet, step down 1-2 jet sizes (factory primary jets: .098", secondary: .095"). For altitudes above 7,000 feet, consider a calibration kit with altitude-specific rods and jets. Q: What's included in the box?A: Complete assembled carburetor, mounting gasket, throttle ball stud, throttle return spring bracket, installation manual, and tuning reference chart.

No adapter required. Air Valve Secondary: Vacuum-operated secondary air valve opens progressively based on engine demand — no bog, no hesitation, just smooth power delivery. No EGR Provision: Clean, simple design without EGR ports — ideal for off-road, racing, or pre-emissions vehicles. For off-road and racing use only where emissions equipment is not required. Tunable Without Disassembly: Externally adjustable idle mixture screws and easily accessible metering rods and jets enable tuning without removing the carburetor from the manifold.

The manual choke design offers several advantages over automatic chokes for performance applications. You get positive, immediate choke control without waiting for an electric element to heat up — essential for engines with aggressive camshafts that need precise cold-start enrichment. The manual cable setup also eliminates a potential failure point (burned-out electric choke) and reduces electrical load on your charging system. For race cars, off-road vehicles, and hot rods where simplicity is key, the manual choke 1405 is the go-to choice. Tuning Guide Idle Mixture: Start with both idle mixture screws 1.5 turns out. Warm engine fully. Adjust each screw for highest vacuum reading, then back out 1/8 turn for best idle quality. Idle Speed: Set curb idle to 700-800 RPM (manual trans) or 650-750 RPM (auto in drive). Verify timing is set correctly before adjusting carb. Metering Rods & Jets: Factory calibration works well for most 350-400ci street engines. For altitude (>5,000 ft), step down one jet size. For high-compression builds, step up one rod size richer. Secondary Air Valve: Adjust pre-load spring tension via the set screw on the passenger side. Lighter tension = earlier secondary opening. Too light = bog. Too heavy = sluggish top end. Float Level: Fuel level should be 7/16" from the top of the float bowl with the engine idling. Adjust via the external needle & seat assembly — no bowl removal needed. Fuel Pressure: Edelbrock-style carbs are sensitive to fuel pressure. Use a regulator set to 5.5 psi maximum. Higher pressure will force the needle off the seat and flood the engine. Frequently Asked Questions Q: What's the difference between the 1405 and 1406 carburetors?A: The 1405 uses a manual choke (cable-operated), while the 1406 uses an electric choke (automatic, 12V). The 1405 is preferred for race cars, off-road vehicles, and applications where the driver wants full choke control. The 1406 is better for daily drivers and street cars where automatic cold-start convenience is desired. Q: Do I need a square bore to spread bore adapter?A: If your intake manifold is a spread bore design (Q-jet pattern), yes. If it's a square bore (Holley/Edelbrock pattern), no. Most aftermarket dual-plane intakes (Edelbrock Performer, Weiand Action Plus, etc.) are square bore and accept this carburetor directly. Q: Will this carburetor work with my stock hood?A: The 1405/1406 has a relatively low profile compared to Holley double pumpers and Dominator carbs. In most applications with a stock or mild drop-base air cleaner, hood clearance is not an issue. Measure from the intake manifold carb pad to the hood for verification. Q: What fuel pump do I need?A: A standard mechanical fuel pump (5-7 psi) with a regulator set to 5.5 psi maximum is ideal. Electric pumps must also be regulated. Do NOT exceed 6.0 psi — these carbs are highly sensitive to over-pressurization. Q: Is this carburetor emissions-legal for street use?A: This carburetor does not have EGR provisions and is intended for off-road, racing, and pre-emissions (pre-1975) vehicles. Check your local emissions regulations before installing on a street-driven vehicle.
