End play is measured with cam in and dial gauge yeah ?
Yeah, on the end that i marked at least 60% of the teeth are thin, burred in some way.
just spoke with engine builder, runs standard pump.
Can't it also be caused by the distributor bottoming out or something ?
I previously posted how to check the end play.
put the plate on the cam
bolt the gear on the cam
stand the cam on end with the gear facing down
use a FEELER GAUGE to measure clearance between plate and cam
something was way fkd up to kill that bronze gear that fast if it does not have a high volume pump.
it is possible the block is incorrectly machined but we won't know until you check the gear mesh . part of it may be that the distributor gear was running off the end of the cam when it is supposed to be centered.
