What are the bearing clearances set to? Some builders will set the clearance to
the high side to get a little more power. This is not advisable for a street
engine because of the issue with oil pressure. Low pressure = a noisy
valvetrain, ask me how I know.
re: oil pump; if you're not running a standard pump then a high-volume pump is
a better choice vs. a high-pressure. If I recall a hi-press pump can have an
adverse affect on the bearings.
Another possibility for low pressure is a faulty lifter(s). One or 2 bad
lifters can drop pressure as much as 10psi, [again ask me how I know].
