low oil pressure rebuilt 318

What were the bearing tolerances you measured when you built it?

What kind of cam and lifters are you running? High lift and certain lifters can expose the oil gallery, bleeding pressure.

i dont remember what the clearences were but the cam is a jegs 441' flat tappet cam with jegs cheapo flat tappet hydro lifters that are a little stubborn to pump up
