COMP Cams Stage 2 LST 251/266 Hydraulic Roller Cam for Manual GM LS3 w/ Aftermarket Pistons

If you're building a Chevrolet Camaro for serious drag racing and want to maximize horsepower, this COMP Cams Stage 2 LST camshaft is a solid choice. It's specifically designed for manual transmission LS3 engines that have already been upgraded with aftermarket pistons featuring valve reliefs. This camshaft aims for the highest possible horsepower in drag race setups while still offering street durability, and it's built to remain stable up to 7500 RPM when paired with COMP Cams' CK and MK kits.

The 'LST' in the name stands for Low Sweep Technology, which helps reduce valvetrain stress and wear, contributing to that 7500 RPM stability. You'll need aftermarket pistons with valve reliefs because the increased lift and duration of this cam mean the valves will travel further into the cylinder bore. This isn't a direct bolt-in for a stock engine; it's part of a performance build where you're already modifying the engine's internals for more power. COMP Cams is well-known for its performance valvetrain components, and this camshaft is a popular option for LS3 builds targeting maximum drag strip performance.

Keep in mind that this camshaft is not CARB approved and cannot be shipped to California. For optimal performance and reliability, it's recommended to use COMP Cams' CK and MK kits, which are designed to work in harmony with this camshaft to achieve its full potential and RPM stability.
