LS7 Stage 4 V2 Hydraulic Roller Camshaft

The Brian Tooley Racing LS7 Stage 4 V2 camshaft is a high-performance upgrade designed for naturally aspirated LS7 engines. Developed in-house with BTR-designed lobes, this camshaft has undergone extensive Spintron testing and Superflow Engine Dynamometer vetting. With specifications of 246/26X degrees duration, .662"/.662" lift, and a 111 LSA, this camshaft is engineered for maximum effort naturally aspirated builds. It is intended for use in conjunction with ported cylinder heads, an aftermarket throttle body, and an intake manifold, such as BTR's Trinity series. This camshaft delivers aggressive idle characteristics and significant top-end power gains, though it may result in a sacrifice of some low-end torque. For optimal performance and reliability, BTR recommends using this camshaft with titanium intake valves. The .660" Lift Platinum spring kit with titanium retainers is a suitable pairing, and a maximum open spring pressure of 430 lbs is recommended. Due to the LS7 rocker arm geometry, up to .660" lift can be used without valve tip damage.
