All Chevrolet Performance LS camshafts are compatible with production-style LSX and C5R blocks, as well as all of our cylinder heads ヨ although piston-to-valve clearance must be checked on some applications. We offer a broad range of production and racing-style camshafts that are factory-engineered to deliver maximum performance when paired with our high-flow cylinder heads. Save yourself the time and expense of going to an aftermarket camshaft supplier and build your LS engine with a genuine GM cam. We’ve also got the valvetrain components you need to finish the engine, including lightweight components designed for high-rpm performance.
