Howards Cams American Muscle Hydraulic Roller Tappet Camshafts
Howards Cams American Muscle hydraulic roller tappet camshafts are designed as near-duplicates of the most iconic OE camshaft grinds. Howards took these fantastic grinds and made slight changes to the ramp speeds—and minor duration changes for better reliability and horsepower. They provide the same throttle response and the original-style exhaust rumble. Howards Cams manufactures American Muscle hydraulic roller tappet camshafts on dedicated, high-precision cam grinding machines to strict tolerances. Each cam is 100 percent Rockwell checked and Parkerized, ensuring the highest quality. Select the model and performance options that best suit your vehicle application.
