Ever since its introduction in 1997, the Chevrolet LS1/GEN III engine has been setting the high performance world on fire with its impressive power output, remarkably low weight, and dramatic response to even minor modifications. But as with many other engines, the GEN III factory camshafts leave something to be desired. In their never-ending quest to build a better mousetrap, the camshaft design experts at COMP Cams® have added three brand-new street solid roller profiles to their already impressive lineup of GEN III-specific cams. Engineered specifically to take advantage of the phenomenal efficiency of the FAST™ LSX™ intake manifold, the newest members of the XFI™ line of GEN III camshafts deliver some of the most aggressive lobe profiles that have ever been designed for street driven Gen III-powered vehicles.The result is massive increases in horsepower output, throttle response, and upper rpm capability over factory hydraulic roller patterns.
