Weiand's Pro-Street Superchargers represent a significant leap in technology for obtaining substantial performance gains (25-40% over stock) while maintaining drive ability and reliability. What's more, Weiand has received a C.A.R.B. exemption covering all 1962-1968 Chevrolet passenger cars and light trucks equipped with carbureted 262-350 c.i.d. small block engines. The kits must be installed with the supplied pulleys as well as an OEM Carburetor and emission controls in order to retain 50-state emissions legality.
All Holley supercharges are 100% tested before shipping.
