Howards Cams American Muscle Hydraulic Flat Tappet Camshafts

5.0 out of 5 stars 8 Customer Reviews

Howards Cams American Muscle hydraulic flat tappet camshafts feature a design that replicates some of the most iconic OE camshaft-grinds from the '60s and early '70s. Howards took these fantastic grinds and made slight changes to the ramp speeds and minor duration changes for better reliability and horsepower without affecting the throttle response and the original-style exhaust rumble. Howards Cams manufactures the American Muscle hydraulic flat tappet camshafts designed for your application on dedicated, high-precision cam grinding machines to strict tolerances.
