your correct, non of them look good. Just got off the phone with hughes engines. Dave suggest there was a blockage or leak some where. Said those bearing clearances nor the single groove bearing main bearings or the heavy oil the cause, but would never suggest to run heavy oil.
Called wiseco and they will only build me 4 pistons minimum. Great, $600 for 4 pistons. I can buy a whole set for the 400 block for real close to that price. That BB build is looking better all the time.
