One other thing some engine builders use loser bearing clearances for high reving motors and put in a high volume,high pressure pump. You could always change the spring in the pump to bring pressure up. usually what causes low oil pressure is lose bearing clearances or you have a bad oil pump thats maybe got a weak spring in it. Usually when u rod on the motor and the let off really fast the oil pressure goes up then u have loose rod bearing clearances. I would replace the oil pump before i would tear into the engine to check bearing clearances. If that doesnt fix it then u either gonna have to pull the motor or u may have a faulty oil pressure sender unit. Try to hook up a oil pressure gauge that uses the old manual sender unit instead of the electronic one. Will give u a more accurate reading... Just a thought
