Offenhauser 5882 Buick 400-430-455 Dual Quad Hi-Rise Manifold

• Holley square bore carburetors (such as the 4150/4160 series)
• Edelbrock carburetors (especially the Performer series, which are based on the Carter AFB design)

Owners typically choose carburetors in the 500–600 CFM range for street performance, although you can use larger carburetors if your engine build and RPM range require it. CFM selection will also depend on your specific engine setup and performance goals. This manifold is not compatible with spread bore carbs like the Rochester Quadrajet without an adapter, and it’s best to stick with square bore models for proper fit and performance.
