Is melonized(SP?) steel a new word for composite materials? I seem to remember that you can use a steel gear, not iron, on a steel billet cam with no problems I had a customer do that years ago on a street steel hydraulic roller cam for a 302 Ford, Comp Cams change the firing order on that cam to the Windsor firing order There where some other problems do to his inexperience on steel camshaft cores, he ate two of the stock distributor gears before buying the correct steel one
