Sounds like a new pressure gauge sender is in order. That actual pressure would be virtually unattainable under normal working operation in your motor (10 psi per 1000 rpm is a good rule of thumb for proper oil pressure, a greater ratio at lower rpm is fine, the opposite, not so much), so it is definitely an improper reading of the gauge. If it is the factory dash gauge you are obtaining these readings from, it is also possible that the needle itself on the gauge cluster has simply loosened slightly, not enough to fall off, but just enough to swing into the improper location. If it is an aftermarket gauge, again, re-check the pressure sender.

What is the operating oil pressure of a 3.8 Chevy engine?

I rebuilt my 231 (3800 series II, 3.8) chevy. I checked the bearing clearances several times, and primed the engine before starting it the first time. the current pressure I am seeing is about 70-80 cold and 45-60 at operating temperature. if you are seeing anything lower than 30, it is likely time for a rebuild. the oil pumps on these engines are crank driven and there is no such thing (for these) as a high pressure pump.
