If you have the engine apart, I would put some .001 bearings in it at least.

Engine hasn't been on road yet.
we ran it on the dyno with Delo 400 15w40 60Ib
oil pressure, I could've screwed the relief valve up we were happy with that pressure, the engine has spray oilers. That was on a std pressure Peterson dry sump pump, since then I have purchased a HV Peterson Pro Rotor with single scavenge return in order to reduce plumbing and I may be able to slow the new pump down for less shafted horsepower loss.
My US engine builder has built a lot of race engines and has a good name, so I will contact him and ask him about the clearances. Its not hard to remove sump and change shells.
