Good To Know

Q: Will this bolt straight onto my stock intake? A: It uses the standard Quadrajet bolt pattern for small block Chevrolet intakes, but double-check your manifold flange before installing. Q: Does it come pre-tuned? A: Idle and mixture settings may need adjustment after installation to match your engine, elevation, and fuel type.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
