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 1969-1985 Chevrolet passenger cars and light trucks equipped with carbureted 262-400 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.

Will work with three V-belt accesory drive pulley systems. Not compatible with serpentine accesory drive systems. Long nose kits fit most short and long water pump applications. Will not fit 1984-1985 Corvette due to rack and pinion clearance problems.
