Anderson Ford Motorsports cams are designed to significantly increase the "rate of acceleration", a term used by cam designers to describe the speed at which the cam lobe begins to open the valve, and similar design characteristics in closing the valve as well. The results are a camshaft that makes a significant improvement in all phases of engine power and performance without interfering with function and advantages of the on-board computer system!
