I have said before in the past about gear wear.
I used to run a HV pump wore out 3 to 4 distributor gears before & switched to a standard volume oil pump, after that switch, no more problems.
In all camshaft changes, I used the same thrust washer. It was not worn.
Might have been just my bad luck, but not too sure.
Mike Kirby says a standard volume oil pump is fine to use, even for high RPM. My high RPM is 7500 @ 40 PSI of oil pressure.
Think my bearing clearances are loose.
Not like a typical SBC 10 PSi per 1000 RPM.
