Howards Cams American Muscle Hydraulic Camshafts are near duplicates of some of the most popular OEM camshaft grinds from the 60s and 70s. Howards Cams took these classic grinds and improved them slightly, increasing ramp speeds and altering durations to provide better horsepower and reliability. These modifications have no effect on throttle response or the iconic muscle car exhaust rumble. Howards Cams American Muscle Camshafts are the perfect choice for restoration projects.
