Oil pressure concern

that is plenty of pressure. I assume you mean at idle when hot? all a small block mopar needs at idle is around 6-8 lbs. if you have 10-15 that's nothing to worry about. I put a 4 in. crank in a 360 to and run valvoline 10-40 on the street, drive ot hard and every day and no problems. I have tore into it once after about 5000 miles and the bearings were just as new as the day I put them in there.
