The COMP Cams High Energy steel stud-mount rocker arm for Chevrolet V8 and V6 small block applications features a 3/8" stud diameter and a 1.5 ratio, compatible with engines from 200–400 ci depending on application. A long slot accommodates higher lift camshafts while helping eliminate noise and slop from worn stock rockers, making these a reliable replacement for stock or high-energy camshaft-equipped engines.
