LS1/LS2 Stage 3 V2 Cam

The LS1/LS2 Stage 3 V2 Cam from Brian Tooley Racing is engineered for serious LS engine builders and performance enthusiasts seeking maximum power gains in street and strip applications. This aftermarket camshaft is designed to replace the factory cam in LS1 and LS2 engines, unlocking significantly higher rpm capability and aggressive valve timing that transforms engine breathing. Whether you're building a high-output crate engine, upgrading an existing LS platform, or preparing for forced induction, this cam delivers the aggressive profile required to support 500+ horsepower naturally aspirated or as part of a supercharged or turbocharged package.

As a Stage 3 design, the LS1/LS2 Stage 3 V2 Cam features a substantial lift and duration increase over factory specifications, optimizing both intake and exhaust events for peak cylinder charging efficiency. The V2 iteration refines the original profile based on real-world dyno testing, ensuring improved low-end torque responsiveness while maintaining top-end power delivery across the entire powerband. The precision-ground lobe geometry and hardened steel construction withstand the rigorous demands of high-rpm operation and increased valve spring pressure, critical factors that separate quality performance cams from inferior alternatives. Installation requires compatible valve springs, pushrods, and rocker arms rated for the increased valve lift—a fundamental consideration that separates competent builds from marginal ones.

This camshaft is best suited for builders committed to a complete top-end package: upgraded springs, hardened pushrods, quality rockers, and supporting bolt-ons like intake manifolds and headers are essential to fully realize performance potential. The LS1/LS2 Stage 3 V2 Cam excels in naturally aspirated street engines targeting 500–600 horsepower, as well as boosted applications where aggressive timing supports higher cylinder pressures. Proper valve lash adjustment, quality machining of the block, and dyno verification are industry-standard practices that maximize longevity and confirm expected power output. This is not a bolt-on for stock engines; it demands a commitment to supporting modifications and knowledgeable installation by experienced builders familiar with LS platform dynamics.
