Vortech Superchargers Tuner Kit V-7 YSi 50mm Cog Polished (Big Block Carbureted Chevy) 4GA218-068

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

Note: Carbureted Tuner Kits do not include Vortech Carburetor Enclosure Box, which a similar box or hat must be sourced separately. Vortech PowerHat also available for purchase separately.
