Our "615" Box Stock/Pro Stock class carb. Airflow has been significantly increased by opening and reshaping the Venturi using a CNC machine - the same technology we use to bore our connecting rods. The carburetor will be jetted for your application. Will pass Box Stock/Pro Stock tech.
You will need to set your engine to idle at approximately 2000 RPM by adjusting the large phillips head plastic idle speed adjustment screw.
