My guess: Either you have the wrong size bearings (could be an align bored
case, for example) or your crank was machined wrong, or you could have left
out a bearing shell, or the oil pump could be worn out. What it comes down
to is you are going to have to take that engine apart, and find out what's
out of tolerance.
