CAM BUTTON CHEV SB ROLLER

Compcams Chev small block .795 inch roller cam buttons ride between the front of the timing gear and the back of the front cover, and can be shimmed for proper endplay of the cam. Because all roller cam lobes are ground flat instead of tapered, like hydraulic or solid cams, it is necessary to provide some means of holding the cam back to the rear of the engine. We also stock COMP Cams solid nylon buttons COM202.
