American Muscle Hydraulic and Mechanical Flat Tappet Camshafts
Near duplicates of some of the most iconic original equipment camshaft grinds from the ‘60s to the early ‘70s. We 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. Grinds available for Chevrolet, Chrysler, Ford, Oldsmobile and Pontiac.
All Howards Cams use the highest-grade race quality cores available. All hydraulic and mechanical flat tappet camshafts are 100% Rockwell checked and Parkerized to ensure the highest quality control standards available anywhere. Howards Cams are manufactured on dedicated high precision CNC cam grinding machines. Most Howards Cams are packaged and shipped in their unique, hard, high impact plastic reusable cases. This ensures that the high quality camshaft that went into the case comes out in the same condition, when delivered, as when it was packed.
