The COMP Cams CS 274L312 S7 camshaft provides a .312" lobe lift optimized for higher-RPM tracks running under .480" or .500" lift restrictions. It offers a rev-happy profile designed for restricted competition while still delivering usable power through the rev range. Note: 1955–57 small-block Chevy engines have a rear-journal oiling groove; request the matching grooved cam if required.
