Crane Camshafts Crane Cams called upon their more than 40 years of computer aided cam lobe profile design experience in developing new Crane Zcams? for popular V-8 engines. New Crane Zcams? are now available for computer-controlled as well as non-computer equipped cars and trucks.

Crane's lobe profile engineering group recently developed and tested these and found that they remarkably exceeded the performance of the highly successful Crane PowerMax? series. The new Zcams? are designed to increase the ?area beneath the lift curve? in each profile. Simply put, new Crane Zcams? begin moving the valve off its seat quicker, to initiate flow earlier. The Zcam? profile lengthens this rate of acceleration during the cycle in which the valve is opening and as it approaches maximum valve lift. At max lift the Zcam? then returns the valve to its seat, but only after maximum flow and cylinder filling has been achieved. Zcams? function like a much ?bigger? cam (greater duration) yet they increase low-end and mid-range torque in the most often used rpm range. Peak horsepower and torque output are enhanced throughout the entire rpm range! New Crane Zcams? were also designed to minimize horsepower-robbing harmonic frequency pulses when matched with the recommended Crane valve springs and pushrods.

These new Crane Zcams? are available in both ?cam only? and ?Cam & Lifter Kits? for standard ?flat-face? hydraulic cams. Hydraulic roller Zcams? are available as cam-only. Crane also offers new hydraulic roller lifters for engines originally equipped with hydraulic roller cams, and as retrofits for earlier non-hydraulic roller engines. Both styles feature easy drop-in installation. Crane retrofit hydraulic roller lifters require special length (shorter) pushrods. These are also available from Crane Cams.

New Crane Zcams? are available in many different profiles, depending on engine family. These begin at relatively mild, streetable profiles and continue upwards to radical profiles for extreme street and all-out race applications.
