I hate to see you ask a general question to engine builders on the internet.
Your going to get everyone in here with their own opinions. I agree with Mikey that it appears that there was not enough oil pressure to maintain a oil wedge in the bearings
It comes down to finding out what happened first. That is the tough part.
How aggresive was the tune? How much timing? A/F ratio?
Also you need to measure the journals at 90 degree points. You need to be sure that the journals are round and that the crank was straight.
Many of the off shore crankshafts need work before they can be properly installed.
Good luck with your situation.

Cam is out and looks brand new still. The tune was not aggressive to me. I had 0 knock to speak of and Even had Texas Speed look over the file and make some adjustments to my Idle, but other than that they said it looked good..
The crank has been checked and does have a little bit of bend after or near the #5and #6 rod rod journal.
I can definately get more pics. The rod bearings look just like the main bearings. Lots of hot spots and scoring.
