It sounds good but seems to have unusually high oil pressure.

The old oil pump used to have 65 LBS hot or cold. The new one has about 75 at idle and seems to go over 100 if you rap it.

I'm using Rotella 15/40 in it. I'm gonna switch to a straight 30 wt.

Switching to straight 30 wt will make the cold pressure even higher. I would stick with the 15W-40.

Put the relief spring from the old pump in the new pump. The new pump spring is likely different.
