Normally, about 20-30psi at idle and up to 70-80psi under WOT higher
RPM...with 60-70psi being normal cruise.
You're well within normal specs.

Subject: DML: oil pressure
What should the oil pressure normally be for a 3.9 at idle? I seem to be
running 30 at idle but at 1500 it rises to around 60. That is after warm
up. I changed oil, Pennzoil 10W30 and Fram filter. I'm not absolutely
sure but I think it ran around 50 at idle, before the oil change. Maybe
this problem is my imagination? [:^)
