COMP Cams Dual Energy 211/221 Hydraulic Flat Tappet Small Kit for Small Block Chevrolet 262-400

Ground with more exhaust duration and lift than the intake, the Dual Energy camshaft grind is designed for applications where a slight sacrifice in low end power is acceptable in exchange for increased mid and upper RPM power. Ideal for use in stock applications with restrictive exhaust systems, the Dual Energy's addition exhaust duration overcomes stock exhaust limitations.
