Brian Tooley Racing naturally aspirated stage III cam features a very wide power range and excellent mid-range torque for the naturally aspirated LS7 engines. Cam specs are 238/250 .652"/.630" 113+3 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.
