Well untill ya put a knowen GOOD test gauge on it and check NOBODY knows for sure. BUT on a 400 sires engine you should have really good oil pressure above 60 psi and no lower then around thirty psi hot at and idle Main , rod and cam bearing Clearance along with the out put of the oil pump gives you the pressure . Now if say someone at some time left out a galley plug or a piston cooling jet was missing then the pressure will be down . So in other words if bearing clearance is at the far end of spec's and the oil pump is getting to far out of spec.'s and also you choise of oil weights there is something not wright with this engine or your gauge . Now wheather the guy that did the engine did it correctly and checked every detail with mic.'s and plasta gauge , made sure that all galley plugs were installed and all cooling jets were in place installed new cam bearing and FIT the cam to the bearings . I have no idea as i did not build the engine I have seen way tomany socalled engine rebuilds that people just slap a kit in them and check nothing and call it GOOD . A good 400 sires engine will peg the gauge and be better then half way up at idle HOT .
