This is a "universal" supercharger kit designed for vehicles equipped with carbureted big block Chevrolet engines.

• This system requires the installer to supply a high volume fuel pump and properly jetted 4150 style carburetor unit (with mechanical secondaries)
• We have verified this kit to fit on 1964-1972 Chevelle / Malibu models equipped with a cowl induction hood. Minor bottom-side hood support modifications may be required depending upon the type of intake manifold installed on the engine.
• This kit may also fit other Chevrolet models, but has not been confirmed
• Horsepower gains (depending on boost levels, engine volumetric efficiency etc.): 30-75%+
• Supplied pulley ratio will produce approximately 5-6 psi at 5000 rpm on a mildly modified 454" engine
• Installation time: 4-10 hours depending on application
