Is the cam austempered steel or billet? Does the came have a press on gear or machined? If the cam is austemepered and does not have a pressed on iron gear then you need a melonized gear for the dizzy. If it is billet and does not have a pressed on iron gear then you need either a bronze gear (which I would not recommend on a street car because they wear out FAST) or the composite gear sold by comp cams (much better gear than bronze).
