The”615″ Box Stock class carburetor airflow has been significantly increased by opening and reshaping the Venturi using a CNC machine – the same technology is used to bore connecting rods.

Will pass box 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.
