Brian Tooley Racing naturally aspirated stage IV cam features a very wide power range and excellent mid-range torque for the naturally aspirated LS1/LS2 engines. This camshaft is very aggressive for a daily driver application.

This camshaft was designed with 16 degrees of overlap. It has an aggressive idle and makes great top end power at the sacrifice of some low end torque. The increased exhaust duration will pull very well in the upper RPM's without power falling off like other cams might. Cam specs are 235/242 .621"/.592" 111+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.
