Specs At A Glance

Good To Know

Q: Will this carburetor bolt straight onto my stock manifold? A: It uses the standard two barrel Rochester 2GC mounting pattern, so it fits factory manifolds built for that style. Check your intake and linkage before ordering to confirm the match.

Q: Do I need to adjust it after installation? A: Idle speed and mixture settings usually need a final tweak once the carburetor is on the engine. Plan on a short tuning session to get the best driveability.

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