Chevy Big-Block V8  |  Camshafts Lifter Kits
 

These new generation of camshaft kits are designed and manufactured by Crane Cam Co.® for GM Parts Division. All kits contain one (1) camshaft and sixteen (16) tappets. A camshaft is the "brain" that controls the flow of fuel and air through an engine. The camshaft's lift, duration, and overlap strongly affect an engine's idle quality, power curve, and rpm potential. GM Performance Parts offers a wide variety of camshafts for bit-block Chevrolets, ranging from low-maintenance hydraulic lifter grinds to full-race mechanical tappet profiles. Many of these cams were originally produced for high-performance engine options; others are intended strictly for off-highway competition. The accompanying specification chart summarizes the vital statistics for big-block V8 camshafts. New camshaft kits are now available that include tappets.
