Frequently Asked Questions
Q: Will this fit my intake manifold?
A: This carburetor has a standard square bore flange pattern that fits most 4-barrel aftermarket and factory intake manifolds. Please check your manifold bolt pattern.
Q: Does it come pre-tuned?
A: Yes, each carburetor is factory-calibrated for a baseline tune on a typical mild V8 application. Fine-tuning (idle mixture, idle speed) may be needed for your specific engine combination.
Q: What fuel pressure is recommended?
A: We recommend 5-7 PSI fuel pressure at the carburetor inlet. Use a quality fuel pressure regulator if your pump exceeds this range.
Q: Is this compatible with ethanol-blended fuels?
A: Yes, the fuel-resistant coatings and seals are compatible with fuels containing up to 10% ethanol (E10). For higher ethanol blends, we recommend additional fuel system upgrades.
Q: Do I need an adapter plate?
A: This carburetor fits standard square bore intake manifolds. If you have a spread bore manifold, you will need a square-to-spread bore adapter (sold separately).
