This is Brian Tooley Racing's Stage 2 LS7 camshaft for naturally aspirated applications. It is a hydraulic roller, 3-bolt camshaft for LS7 engines.
Specs: 230/25X, .650"/.650", 116 LSA
Developed in-house using BTR designed lobes, the new Stage 2 cam is the latest offering in the LS7 line up. We went back to the drawing board to find even more power and torque. This V2 version of our Stage 2 LS7 camshaft makes more power and torque everywhere in the curve compared to our previous Stage 2 LS7 camshaft. This camshaft has a moderate idle and makes great top end power at the sacrifice of some low end torque.
These new BTR lobe designs were Spintron and Engine Dyno tested to achieve the highest overall power curve while also maintaining strict valvetrain stability and durability standards.
Requires the use of our .660" Lift Platinum spring kit with titanium retainers and hardened pushrods. 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.
For maximum performance and reliability, we recommend our LS7 camshafts be used with titanium intake valves.
