I had a similar problem when I built my new motor. However, I sheared the
roll pin in the distributor gear a couple of times before it was corrected.
1. Our assumptions: the high volume pump with higher viscosity oil put a
big load on the pin. So I changed the oil to 5w-30 and go the oil pressure
to drop into the reasonable range 50 at idle and 75 under normal load.
2. We finally ended up shaving .010" off the bottom of the gear. The
tolerance seemed to be too tight and was loading the gear up. Once we did
this I have had no further problem. It's been this way for the last 5K
miles or so. I was shearing the pins within 500 miles before.
The hole for your distributor gear might be off slightly from your old one,
but the tolerances would pass QA and still give you a problem
