The average 408...

What about the spring? I think Hughes is pulling your leg (Imagine that), I have had wore *** out 360's, with more pressure than that. I have built "loose" engines before, and ran wore out bottom ends to the point of knocking before the 20W50 reached the bearings, and they were at least 10psi per 1K. Is it a hughes engine?

Every Mopar SB I have built had 75psi by 5K. Not dogging your motor, I just wonder if the cam bearings are loose, or something, mains? I just dont want to see a thread here next year..... My motor blew up. You know, watchin' out for ya.

Correction: I just understood the spring question. And another thing: The oil pump that's in my engine now is a standard volume melling oil pump. I never switched to a high volume, I thought I did, but we didn't do that. SO, maybe if I switch the oil pressure relief spring to a stiffer one, this could possibly fix the problem...

I've just read in my "how to hot rod small block mopar" book that the stock oil pump and spring tends to run at a max of 50 psi. If I were to change it to a high performance unit I'd be at 70 psi.

So, I think that's what it could be.
