Crane Camshaft
Camshaft; For Use With 1970-1978 Chrysler 383-440 Engines
MPN: 688531
Designed for operation at ranges that can exceed 10,000 RPM, mechanical roller cams represent the ultimate in efficiency. While a large number of mechanical roller cams are used in purely competition applications, Crane Cams does manufacture less severe roller grinds that are designed for high performance street engines that have higher compression or power-adders. For best results, valve lash must be checked and set periodically.
