The “Mr. Horsepower” legacy began in the early 1930s 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.
