Got the block back from the machine shop right before we left for Norwalk. Seems my friend who does machine work out of RI didn't exactly get my line bore/hone right. The #4 main was slightly egg shaped and that is what caused the main bearing saddle to go out of round by two thousands. When checked with a snap guage, everything looked good. It was only after the motor was started that the bearing moved, most likely pinching off the oil supply (explains the sudden loss of oil pressure) and hence wiping out the #5 rod bearing.
I want to make it very clear that IA did not line bore the block, therefore, it cannot be attributed to them or their machine work. They took a motor that was worked on by someone else and tried to help me out. Next time will be different.
