Brian Tooley Racing Gen III-Gen IV LSx BTR LS7 Stage 4 NA Cam 34758123
BTR LS7 STAGE IV CAMThis camshaft is very aggressive and should only be used on maximum effort combinations. This cam has made 600+ RWHP in a few setups, but attention to detail must be paid to attain those results. It has a very aggressive idle, and makes great top end power at the sacrifice of some low end torque. Cam specs are 247/258 112+3 and comes a 3 bolt timing gear pattern. Our .660" Lift Platinum spring kit with titanium retainers work great with this camshaft.
Due to the longer pivot length and longer scroll of the LS7 rocker arms up to .660" lift can be used without valve tip damage. We recommend maximum open spring pressure of 430 lbs.
