Its really weird.
I ran a stock distributor for several years after building this enging with NO problems for several months.
First time I noticed a problem, my tach was jumping up and down while running a constant speed. I pulled the distributor and found the teeth of the distributor gear as sharp as a razor blade ! I replaced the complete distributor with an Accel distributor, same problem, sharp teeth on gear after SHORT time.
Soooo, I went back to origional OEM distributor for a try. Ran great for a while then sheered the pin on the distributor gear. replaced pin, (checked out
oil pump and removed pan to verify no "debri" floating around from pin/gear damage) . Installed new pin, OK for a couple months (2/3 short drives) and POW pin sheered again !
Whats the best way to check to see that the gear is properly alinged with the cam gear? Depth? etc.
Also, could this be a cam problem causing this? Its a competiton cam 280 duration 530 lift, not to radical but healthy.
Thanks guys!
