I read your first post - and I understand that you only have 10K on the new motor. I was trying to help out in a roundabout way... I'm no oil pressure expert, I was hoping to get you to post your actual numbers so somebody who DOES know the causes/cures for low oil pressure would read your post more carefully. Sometimes the EXPERTS won't respond to posts without details that will help them diagnose the problem.

Also, if you use the search feature, there are MANY posts about oil pressure levels (what is normal for specific combos - and possible cures).

I recall seeing the rule of thumb as 10psi per 1000rpm.

It would help to know your psi readings at WOT and Idle - both cold and warm engine.
