The Melling Class 3 Camshaft with a 226°/238° duration at .050" and .625" lift on both intake and exhaust is built for serious LS performance enthusiasts targeting a street/strip setup. Designed with a 112° lobe separation angle, this camshaft delivers a strong mid-to-high RPM powerband while producing a noticeably aggressive, choppy idle. It is configured for 3-bolt cam gear setups and is only compatible with non-AFM (Active Fuel Management) LS engines. This camshaft is best paired with manual transmissions or automatics equipped with high-stall converters to fully take advantage of its performance potential. Supporting modifications are essential, including upgraded valve springs to accommodate the high lift, performance pushrods and lifters, and a properly tuned ECU to ensure smooth drivability and optimal power output. This cam is a solid choice for builders seeking a race-inspired sound and performance in a street-capable package
