Specs At A Glance

Good To Know

Q: Will this bolt directly to my stock intake? A: It is designed to match the Quadrajet flange pattern used on many Chevy 305 and 350 intake manifolds, but verify your flange style before ordering.

Q: Does it come pre-tuned? A: Carburetors typically need idle and mixture adjustment after installation to match your engine and altitude.

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