Oil Pressure??
Any body know the approx oil pressure reading for a 390.Not sure what it is, the engine was just "professonally"rebuilt?

Oil Pressure??
It will depend on a couple of things:
1). The relief valve in the oil pump - this determines your max. pressure.
2). The volume of oil the pump can pump.
3). The clearance of the bearings.
4). The viscosity of the oil
5). The temperature of the oil.
These determine the minimum pressure, it can be quite low, but on a new motor I'd be surprised if it was less than 30.
At least that was my experience when I last overhauled an FE motor 25 years ago.
