Melling Camshaft LS Class 3, 220/224, 3 Bolt/Non AFM .575/.575 Lift, 112 Lobe, Each is designed for performance applications in GM LS engines without Active Fuel Management (AFM). It features a 3-bolt mounting design and delivers a duration of 218° intake and 224° exhaust at 0.050" lift, with an aggressive .604"/.604" valve lift on both intake and exhaust. The camshaft has a 112° lobe separation angle, providing a lopey, rough idle and strong mid to high RPM horsepower and torque. It is ideal for vehicles with manual transmissions or high-stall automatic converters, and typically requires supporting upgrades like enhanced fuel, exhaust, and ignition systems. Due to its aggressive profile, it also produces reduced engine vacuum, which may affect power brake operation and other vacuum-assisted components
