Evidently this is less oil pressure than this engine had when ran before or you probaly would'nt be concerned about it? I ran and seen lots of engines live long lifes with that pressure.
If this is lower than engine had before,does it have main studs or have you changed to a stud set? The reason I'm asking this is because BBC main studs alot of them have a 12 point nut that goes next to oil pump,because the hex nut alot of times won't clear the oil pump and will hold pump off main cap.
If nothing else is wrong and you have HV pump w/hi press.spring that comes in them you probaly have about .004-.0045 bearing clearance
std. vol std.press pump you probaly have about .003-.0035 bearing clearance,that is if you don't have leak somewhere.
I would test pump before I bought another one installed it and had same results,if pump puts out around 60 lbs then you know it's not the problem.
