Brian Tooley Racing positive displacement supercharged stage III cam features a very wide power range and excellent mid-range torque for LSA, LS9 and LS3 engines with positive displacement superchargers. This cam is on the upper end of aggressiveness for GM LSA and LS9 engines. It will work great with any positive displacement supercharger on a 6.2 liter engine. With almost 0 degrees of overlap it has a definite camshaft sound, but still has a mild idle, yet makes the power of much larger cams. The secret is in minimizing the overlap, while maximizing the intake valve closing and exhaust valve opening events.

This cam has proven to make more power than other cams that have more lift, which makes this cam much more durable. Cam specs are 231/248 .617"/.595" 120+5 and comes a 3 bolt timing gear pattern.

Note: Dual valve spring and retainer package is required with this camshaft. We also suggest 1-piece hardened pushrods along with the COMP Cams 13702-KIT Trunnion upgrade kit. JDP Motorsports recommends degreeing the camshaft and checking piston to valve clearance when installing any aftermarket camshaft.
