So from gathering this info looks as if ill just throw her on with the standard 1/16 hole.

I know Oil pressure plays a big part in the sizing since a higher pressure will feed more oil through the hole.

Whats your oil pressure like?

Thank you for the info

The regulator on my Function7 flange is basically a a 1/16 inch hole which can be drilled out to increase oil flow.

Hmmm, currently your running smaller than 1/16"
Whats your oil pressure like?

Im installing a ported Melling Oil Pump on the 370 im building so i may have to go with a small hole as well.

Thanks,
Derek
I'm at 55 psi on a cold start, about 45-50 with a warm engine at idle. 65-70 at higher RPMs. I'm running straight 40 weight oil.
