88 Z28 bearings out on the crank
I just bought a 88 z28 camaro and it has the tpi. it is bored 30 over and not sure why it blew up. but all the bearings went out on the bottom end. it was recently rebuilt and had less than 10 miles on the run. not sure what went wrong. looking for thoughts. not sure what it has for a cam if its original or not. thinking not. i need some thoughts.

Serveral possible answers as to why it blew:
1: Bearings installed incorrectly
2: Bearings installed DRY with no assembly lube
3: faulty oiling system (bad pump, blocked oil passages ect....this could go along with #1, Bearings installed backwards ect could block the oil passages that feed the bearings.)
4: Bearing tolerances could have been too tight or too loose.
