To make a long story short, the engine didnt make 21 hours, before having to come out. Turns out they built it, but the clearances were so friggin tight, it ate the bearings right out of it. No oil pressure at warm idle was the clue. Had a total rebuild done by Ateco and no more issues after that. They used all decent parts, Dart block, Steel cranks, H beam rods, etc etc. Just poor assembly/machine work.
