Description
If you’re running a Holley 4150 carb and want to unlock higher airflow capacity, this retrofit kit eliminates the need for a complete carburetor swap. The HP main body upgrade transforms your existing 750 CFM carburetor into a higher-performance unit without replacing the entire assembly—a cost-effective solution for serious street and competition builds. By upgrading to an HP-spec main body, you’ll improve throttle response and fuel delivery consistency across your engine’s RPM range.
