    drove it around quite a bit today and zero issues ran great. Oil pressure seems a little low for a brand new motor ( 20 psi @ idle @ 190 deg, 50 psi @ 2,500 ) I'm gonna change it tomorrow

    Good deal, gotta love a great running engine. I wouldn't be too worried about that oil pressure unless you build it with some pretty tight clearances or have a high psi pump.
