STAGE 1: Supercharger Porting Package

This Package is best suited for the 289-357 cubic inches range with a port matched intake manifold, upgraded fuel system and free flowing exhaust system. A mild cam or 1.72 ratio rocker arms will add more horsepower. Although this package works exceptionally well on naturally aspirated engines, it was designed for maximum power with a supercharger system running between 6 to 12 pounds of boost pressure.
