The Melling Camshaft LS Class 4, 236/246, .612"/.612" Lift, 110° Lobe Separation is designed for high-performance applications in GM Gen III and IV LS engines, including 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L engines. This cam features a hydraulic roller design with a 3-bolt configuration, making it ideal for non-AFM and non-VVT applications. With a valve lift of .612" on both the intake and exhaust, and a duration of 236°/246° at .050", it provides aggressive performance for those looking for significant power gains in the mid-to-high RPM range. The 110° lobe separation angle further enhances this cam’s ability to deliver strong power, particularly at higher RPMs. While it creates a rough idle and may not provide adequate vacuum for power accessories, it’s perfect for race or off-road builds where a high-stall torque converter or manual transmission is used. Emissions-legal use is not permitted, as this camshaft is intended for off-road or competition use only.
