The COMP Cams CS 273L283 S7 camshaft features a .283" lobe lift tailored for higher-RPM tracks under .425" or .450" lift restrictions. It provides a higher-revving profile within spec for restricted classes while preserving usable power. Note: 1955–57 small-block Chevy models have a rear-journal oiling groove; order the proper grooved cam if your application requires it.
