Default Oil pressure

What should oil pressure be at idle when warm? im running royal purple 20/50, i installed a manual oil pressure gauge and at idle im getting 8-10 lbs. then my check gauges light comes on. i have a 408 stroker, i had the oil set out for testing and it came back very clean, they said absolutely NO foreign substance in the oil. so im ruling out bearings. Could the oil pump go bad? any thoughts would be great thanks in advance..

I moved your thread here where more of the mechanical people tend to look but I would think your oil pressure should be in the 19-20 psi range so your pressure does sound a bit low. Could be the pump or the sending unit. Since your gauge is relatively new, doesn't sound like that would be it but hopefully others here will have some advice for you.
