    Question Distributor gear question

     



    Hello - I have purchased a Chevy crate motor (2 yrs ago). Its a 454 HO with a hydraulic roller cam. I suspect that being a roller it is a steel cam. I also have a MSD distributor with a black distributor gear (I assume that this is steel also). Should I be running a bronze distributor gear?

    BTW - It has a chevy alum intake thats junk. It got terrible casting lines and .15 of slop in the distributor hole. Anyone have a Edellbrock air gap or performer RPM for rectangular heads they want to part with?

    It case anyone wants to know. I bought the melonized GM dist gear and I'm having the shaft hole enlarged to .500 in to fit the MSD distributor. The gear was $39. Don't know what the machining will cost. The GM hole is .491 in.
