hey guys i was working on my dads 1963 corvette and been built engine like past in 2005 its 327 cubic v8 he dont drive that much due of low oil pressure. Last night I replace the oil pump to melling high volume oil pump and put on. Put new oil and oil filter. Got running. At idle low pressure. But when drive give some gas it go to 30 psi which is good. But at idle it drop real low like 5 psi. What do you have any idea why it cause? I want to solve this problem.

Could be a bunch of different problems.Bad Bearings,Pick up came off or the pressure gauge could be no good if both oil pumps read low.
