Specs At A Glance

Good To Know

Q: Is this an original Rochester Quadrajet carburetor? A: No, this is an aftermarket replacement carburetor built to fit Rochester Quadrajet applications and is not an original brand unit. It is sold as a direct replacement part only.

Q: Do I need to adjust anything after installation? A: Idle speed, idle mixture, and fast idle settings typically need to be checked and dialed in once the carburetor is mounted and the electric choke is wired. Verify throttle and kickdown linkage travel before driving.

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