You will need to use a steel or bronze gear with the steel core camshafts. The steel is what we use in the street engine because they will wear better over the long haul and not need replaced like a bronze eventually will. The Comp Cams polymier gear will work I just had a few guys strip the gears in the samll blocks but have not tried it on a FE engine. If Crane has a steel gear to fit your distributor that is what I would go with. Good luck, Keith Craft
