I wouldn't use a high volume or high pressure
oil pump UNLESS I knew and had PLANNED to increase all internal clearances to max allowed. Making the engine "loose" and thus requiring a high volume pump due to LOSS' because of the big clearances.
I'm not sure a guy even needs 80 psi as far as that goes. Jamo was running 50 wt
oil when he lost his dist gear. I don't know, you think there's a connection?
