LS3 Stage 4 V2 Cam

The Brian Tooley Racing LS3 Stage 4 V2 Cam is a high-performance hydraulic roller camshaft engineered for serious LS-series engine builders and performance enthusiasts. This camshaft delivers the aggressive valve lift and extended duration necessary to maximize horsepower and torque in naturally aspirated and forced-induction LS3 applications. Whether you're building a street performance engine, weekend track car, or high-output crate motor, the Stage 4 V2 provides the mechanical foundation for significant power gains across a usable RPM band.

Featuring 0.636-inch lift on both intake and exhaust lobes with a 233-degree intake duration and 111-degree lobe separation angle (LSA), this cam is optimized for mid-to-high RPM performance while maintaining drivability characteristics suitable for street use. The hydraulic roller design eliminates friction losses inherent in flat-tappet designs, ensuring consistent valve actuation and reduced wear on valvetrain components. The 2000–7300 RPM operating range suits both cruise-and-drive scenarios and sustained high-load conditions, making it a versatile choice for builders seeking balance between daily driveability and peak performance output.

The LS3 Stage 4 V2 Cam is ideal for engine builders, performance shops, and DIY enthusiasts upgrading LS-series engines in Corvettes, Camaros, Silverados, and Gen IV/V swap platforms. Installation requires proper valve clearance adjustment, quality pushrods, and a valve spring package rated for the lift and RPM specifications. Pairing this camshaft with complementary cylinder head work, intake manifold upgrades, and tuning optimization delivers measurable gains in horsepower and throttle response. Verify compatibility with your existing valvetrain components and consult Brian Tooley Racing specifications before installation to ensure proper fit and performance.
