That would be a pretty freak failure. The stock crank is pretty good, guys have no problem whatsoever doubling the stock power and more on the stock crank.
Was the car hit in the front and the crank was hit maybe? I looked at a motor in a car once and the core support was an inch from the balancer and I was sure it had touched on impact. Could it have had an aftermarket crank? Eagle cast cranks are popular in rebuilds and are a BIG step backwards from stock.

Hi the car was hit in the side rear motor totally stock the bearing fell out there was no wear so the motor had 38000 miles. I will post pics when I h be enough posts I am worried I have a 94 corvette n lt1's r good motors. I just found a replacement motor from a 95 ss but this motor I will do a timing chain n cam roller rockers hope I don't have issues got me worried I have 2 ls motors hanging around but I have aready spent the money for thelt1 harness trans n ecu

very off failure on a stock LT1. maybe if something in the drivetrain "suddenly" locked up but still very rare for a crank to snap
It is possible that the donor car accident was the initial cause possibly resulting in a crack in crank that finally let go...

It would be like an oiled saw… works very well.
