Oil pressure question??

SB 4 bolt 350, how much oil pressure should I be running at idle, which I have at 900 rpm and how much say at 3400 rpm's which is about 65 mph? I am thinking my oil pump is not pumping as it should. I'm running 10/40 Valvoline. It will pump up real slow to about 35 lbs then as the oil heats it drops. Just curious what is normal. At temp it will Idle at about 15 to 20, at speed about 25 lbs. Normally operates at about 185 deg. I have an Autometer OP gage. Thanks, Mike
