BTR LS3 Stage I NA Camshaft (32128122)

Regular price $389.00

Brian Tooley Racing naturally aspirated stage 1 cam features a very wide power range and excellent mid-range torque for the naturally aspirated LS3 engines. This camshaft is great for those wanting the power production of the Stage II camshaft, yet desire slightly better driveability. Cam specs are 221/228 .609"/.571" 112+2.

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.
