Why do one-grind-fits-all? That's why Crane Cams developed their line of Zcam hydraulic roller camshafts for the 5.7 and 6.1 Hemi Magnum engines. Zcam's available in a mild street/towing profile or an aggressive design for street/strip applications. All are dual-pattern designs-individually optimizing intake and exhaust lobes. They're manufactured using new 8620 steel cores that are heat-treated, carburized, and precision ground to the industry's most stringent quality control standards. Catalog grinds range from a smooth-idling, torque-oriented 210/216-degrees of intake and exhaust duration at .050 inch, and .550-inch lift cam with 112-degree lobe centers to an aggressive, somewhat-choppy-idling 222/228 degrees duration at .050 inch and .500-inch lift with 114-degree lobe center bruiser that's designed for use with improved valvesprings and computer upgrades. Crane also offers custom grinds for the 5.7L and 6.1L Hemis made to your specifications.
