I need some advice. My engine builder assembled my 499 stroker. The bearing clearances are on the loose side with the rods at .0026-.0027, and the mains are .0031-.0032 and number 3 bearing at .0034. I ran a standard psi/standard volume melling pump. Oil pressure at 6000 rpm on the dyno was at 53 psi, but the engine was only 160 f.

Before installing the engine I replaced the oil spring to a high pressure spring.

Now that I have the motor in the car and the ambient is 90f and running at 195f water, I can tell that the oil pressure is lower. At idle it is at 15 psi and 5000 rpm it is 53 psi. I haven't taken it to 6000 rpm yet but I can't see getting more oil pressure than that. When you increase the rpm the oil pressure does react quickly.

Is this okay to leave it like this or should I be looking at a high volume pump?
