Howards Cams American Muscle Hydraulic Flat Tappet Camshaft
Near duplicates of some of the most iconic original equipment camshaft grinds from the '60's to the early '70's. Howards Cams took these fantastic grinds and made slight changes to the ramp speeds and minor duration changes to give you better reliability and horsepower. You still get the same throttle response and of course the original style exhaust rumble. Great cams for restoration projects and perfect for the street machines.
