Developed in-house using BTR designed lobes, the new Stage 1 cam is the latest offering in the LS7 line up. The all new BTR Stage 1 LS7 camshaft makes more power and torque everywhere in the curve compared to the OEM factory camshaft. This camshaft still has a mild idle with great driveability for daily driving , yet makes significantly more midrange and top end power with almost 70 more horsepower at peak.

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.
