LS3 Stage 3 V2 Cam

The LS3 Stage 3 V2 Cam from Brian Tooley Racing is engineered for serious LS engine builders and street/strip enthusiasts who demand aggressive valve timing and maximum cylinder head flow. This hydraulic roller cam sits at the intersection of street drivability and high-RPM performance, designed to unlock the full potential of LS3 platforms running moderate to aggressive builds. Whether you're upgrading a stock LS3 or complementing a complete cylinder head and intake package, the Stage 3 V2 delivers the cam profile needed to support 550+ horsepower applications.

The Stage 3 V2 profile features increased valve lift and extended duration compared to factory specifications, optimizing overlap and scavenging for enhanced breathing throughout the RPM band. Brian Tooley Racing's engineering focuses on lobe design and ramp rates that reduce valvetrain stress while promoting efficient exhaust evacuation and fresh charge induction. This hydraulic roller design maintains OEM-style hydraulic lash adjustment, eliminating the need for costly lifter upgrades on most bolt-together builds. The cam's geometry is specifically tuned to work seamlessly with stock LS3 cylinder heads or aftermarket castings, provided supporting modifications—like appropriate fuel mapping and ignition tuning—are addressed.

Installation requires proper valve spring pressure verification and pushrod length confirmation to ensure zero clearance issues and sustained performance under load. Builders should confirm their cylinder heads can support the increased valve lift without valve-to-piston or valve-to-head contact. The LS3 Stage 3 V2 Cam pairs best with quality valvespring kits, quality rocker arms, and precision cylinder head work. This is a true performance upgrade for amateur and professional engine builders alike—not a bolt-and-forget component—and deserves installation by technicians familiar with LS platform assembly specifications.
