Brian Tooley Racing naturally aspirated stage IV cam features a very wide power range and excellent mid-range torque for the naturally aspirated LS3 engines. This camshaft has made over 500 rwhp in "cam only" applications. This is designed as a maximum effort camshaft while maintaining acceptable piston to valve clearance. With it's conservative lift it is easy on valve springs and valve tips. Cam specs are 233/248 .619"/.595" 113+5.

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.
