This hydraulic roller camshaft is designed by the GM Racing Division for road racing applications in the Grand-Am series. Serious duration and lift will require that the piston to valve clearance be checked as well as major PCM modifications. For best torque, install the intake centerline at 105; for best power install at 107. GM recommends lightweight valves and valve springs from the 2002-03 LS6 engine for use with this camshaft.

Note: When degreeing this camshaft, it is critical that you use the point of maximum lift on the intake lobe. This is not a symmetrical lobe design!
