Specs At A Glance

Good To Know

Q: Will this carburetor bolt directly onto my Chevy intake manifold? A: It uses the standard Quadrajet spread-bore flange, so it matches intakes cut for a Rochester Quadrajet. Confirm your manifold pattern and throttle linkage before ordering.

Q: Does this carburetor need tuning after installation? A: Idle mixture, float level, and choke settings often need adjustment once installed. Fine tuning is recommended for best driveability on your specific engine combination.

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