I had this cam in my LS7 for a few years. It's got about 5,000 miles on it. I'm asking 250 shipped. PM me for more info..


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.

Cam Specs:
Advertised Duration Int - 294 Exh - 306
Dur. @ 0.050" Int - 239 Exh - 251
Lift w/1.7 Int 0.570" Exh 0.570"
LSA 106

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!
