Oil pressure

My small block ford has 80 psi cold at idle around 1200 rpm, drops to around 65 to 70 psi warm. I am running a Melling high volume pump and 10/30 oil, what is your bearing clearance? in my experience 80 psi is not uncommon to see with a cold engine and a high volume pump in a small block with .002 bearing clearance. I have heard it said that you want to see 10 psi per 1000 rpm. Mine goes through the traps in the 7000 rpm range with about 85 psi.
