LS3 Stage 3 V2 Cam

The LS3 Stage 3 V2 Cam from Brian Tooley Racing is a precision-engineered camshaft designed for high-performance LS engine builds demanding aggressive power delivery and elevated RPM capability. Built for enthusiasts and builders who've moved beyond bolt-on modifications, this Stage 3 profile bridges the gap between streetable driveability and race-focused performance. If you're planning a serious power increase on your sixth-generation small-block—whether for a restomod, drag strip competitor, or weekend warrior—the LS3 Stage 3 V2 Cam delivers the valve timing geometry required to unlock cylinder head flow potential and maximize horsepower across the mid-to-high RPM band.

This camshaft features an optimized lobe profile that increases valve lift and extends event duration compared to stock specifications, improving volumetric efficiency and fuel mixture scavenging. The V2 iteration reflects Brian Tooley Racing's continuous refinement process, incorporating feedback from thousands of dyno sessions and street applications. The aggressive profile works synergistically with cylinder head porting, intake manifold selection, and tuning calibration; without supporting modifications, performance gains remain modest. Cast from premium ductile iron and precision-ground to tolerances, the LS3 Stage 3 V2 Cam resists wear and maintains lobe integrity under sustained high-RPM operation and elevated boost conditions when paired with forced-induction setups.

LS3 Stage 3 V2 Cam installation is straightforward for experienced builders and professional shops equipped with proper cam timing tools and a degree wheel. This profile demands quality roller lifters, a beehive or dual-spring valvetrain rated for aggressive duration, and potentially a custom tune to optimize ignition and fuel curves for peak performance. Compatibility extends across LS3 engines in Corvettes, Camaros, and engine-swapped chassis; verify your cylinder head casting number and confirm supporting components before purchase. Brian Tooley Racing backs this camshaft with comprehensive technical support and installation guidance, ensuring your build achieves intended results.
