These Ford Racing guys live, eat, and sleep Ford. Their camshafts are designed for everything from mildly modified street rods to full-out drag race cars. All of these cams result in an engine that has considerably more power, and yet retains the function and advantages of the computer system. With similar research on their other cams, Ford Racing designs these dual-pattern cams for either low-to-mid rpm torque or mid-to-high rpm horsepower. They're available in many different durations and valve lifts, in your choice of hydraulic, solid, or hydraulic roller lifter camshafts.
