Description
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.
Application Summary
Fits Chevrolet GEN 1 Small Blocks including the 262, 265, 267, 283, 302, 305, 307, 327, 350 and 400. Does not fit LT1/LT4, or factory roller Small Blocks built from 1985 and newer. GM gradually added roller camshafts to 305's and 350's from the mid 80's forward. Camaros/Firebirds/Corvettes received the roller cams early, but many trucks and SUV's had flat tappet cams until the mid 90's. Remove the intake or timing cover to confirm whether the block is a factory roller or flat tappet. Does not fit the LS1, LS2, LS3 or any LS-based 4.8, 5.3, 5.7, 6.0 and 6.2. 1955-1957 Chevrolet 265 engines require a groove on the 5th cam journal for oiling. Contact us for more information.
