The Melling Class 3 Hydraulic Roller Camshaft is designed for GM LS engines without Active Fuel Management (AFM). This camshaft features a 3-bolt attachment style, with intake and exhaust durations of 218° and 224° at 0.050" lift, respectively. Both intake and exhaust valve lifts are 0.604", and it has a lobe separation angle of 112°. This configuration offers a rough idle quality and is suitable for applications requiring good mid to high RPM torque and horsepower. It's recommended for use with manual transmissions or high stall automatic transmissions and may necessitate upgrades to the carburetor, exhaust, and ignition systems. Additionally, this camshaft will have lower vacuum than stock, which could affect power accessories.
