I took a quick look around on the net and I do see that most are reporting around 30 PSI at idle. I can tell you that hot we do not see that on our engines, but it may be a gage issue? We run our engines long and hard and have not had any oil related failures...knock on wood. We run the specified Mobil 1 oil. We run a partial dry sump system that still uses the stock pump for block pressurization, so it should be the same as any other wet sump crate engine as far as oil pressure is concerned.

All that said, I think I would check your gage and then also check the blue o ring at the pump that is commonly pinched or cut on installation before getting too crazy with tearing your engine apart. Next thing I would check is the thrust bearing tolerances, which, IIRC, can be done with a feeler gage after removing the oil pan.
