The “Mr. Horsepower” legacy began in the early 1930’s with camshafts that were literally hand-ground by Clay Smith to high performance specifications. His technical expertise was recognized by the industry and racers were mesmerized by the overall performance of his products. Although he specialized in camshafts, his high performance engines were setting world speed records. He raced Joe Guess’s Hydro boat and during this time a friend of theirs drew a characterization of Clay Smith – which is the now the very famous “Mr. Horsepower Logo”. When you want the best, trust "Mr. Horsepower" and all the pros at Clay Smith Cams.
