Magnum camshafts generate great high RPM power. They can be used with mild ratio rocker arms and traditional performance valve springs as they are easy on valve train parts. The Magnum camshafts generally like compression ratios of 9.5:1 and higher. A torque converter and gear change are usually recommended additional upgrades. The larger Magnum camshafts tend to be a little lazy at low RPMs.
The Magnum 284HR camshaft is the largest camshaft that should be used with stock cylinder heads and intake manifold. Street machines benefit greatly from the 284HR thanks to the good torque it creates. Although the RPM range is rather mild, best power is made above 3500 RPMs. This hydraulic roller camshaft is meant to be used with hydraulic roller lifters.
