Magnum camshafts are specifically designed for racing or high performance street applications by engine builders looking for more power and that Pro Street sound. In addition, engine idle characteristics will change significantly due to the increased duration and overlap specifications of the camshaft. Magnum cams are high performance components. Using a Magnum 280 camshaft can net as much as 100 additional peak engine Horsepower. Magnum 292 and 305 camshafts can generate even more power but require piston to valve clearance checks and the installation of a higher performing torque converter for automatic transmission equipped vehicles. Magnum camshafts may work with new stock lifters, however, we recommend that you use COMP Cams® high performance lifters due to their higher quality and specifically designed bleed rate.
