The fiber gear was common in the passanger engines. The HEI does use a smaller diameter dist shaft. The stock dist has a larger dia shaft that fits tighter in oil pump drive passage. So any deflection will show up as a wobble, as the HEI shaft is supported by its shaft bushings and the top of the oil pump. The stock dist is supported by the same thing, but is a 'closer' fit in the oil pump shaft passage. But since I saw wear on the stock dist gear after only a few minutes of running, I assume that the cam gear is trying to chew it up.
Cam is coming out. We'll see what condition its in. But did cam kill dist or what?
