Brian Tooley Naturally Aspirated LS1/LS2 Stage 4 Camshaft

This camshaft is very aggressive for a daily driver application. Although it's been reported to run at 1200 RPM in 6th gear, very good tuning would be required. 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.

Lift approaching .650" or more while using stock 15 degree rocker arms with too much open spring pressure can damage valve tips long term. We recommend maximum lift of .630" and maximum open pressure of 400 lbs when using stock rocker arms.
