LS1/LS2 Stage 3 V2 Cam

The LS1/LS2 Stage 3 V2 Cam from Brian Tooley Racing is a high-performance hydraulic roller camshaft engineered for serious LS-series engine builders and performance enthusiasts. This camshaft is designed for applications requiring aggressive valve timing and extended duration, making it ideal for street performance, mild competition builds, and tuned naturally aspirated engines seeking measurable horsepower and torque gains. Stage 3 specifications place this cam in the upper-mid performance range—beyond bolt-on modifications but short of all-out racing duty.

The LS1/LS2 Stage 3 V2 Cam delivers 0.636 inches of lift on both intake and exhaust sides, with a 227-degree intake duration and 111.5-degree lobe separation angle (LSA). This aggressive profile increases valve overlap and dwell time, promoting cylinder scavenging and peak power at higher RPM ranges. The hydraulic roller design reduces friction compared to flat-tappet designs, extends valve train component life, and allows use of standard OEM rocker arms and lifters—eliminating costly top-end modifications while maintaining reliability. Brian Tooley Racing's precision manufacturing and quality control ensure consistent lobe profiles and proper clearances, critical for durability under sustained high-RPM operation.

This camshaft is compatible with all first-generation LS1 and LS2 engines (1997–2006 Corvettes, Camaros, and truck variants), and with most LS-based stroker platforms using standard LS valve train geometry. Installation requires a degree wheel and dial indicator for proper indexing to optimize power band characteristics relative to fuel mapping and induction system tuning. Users should verify piston-to-valve clearance and confirm lifter preload before engine startup. The 11.45-pound weight is typical for LS-series hydraulic roller cams and poses no installation interference concerns.
