FWIW, In almost 50 years or repairing cars, and racing them, I once had a customer bring me a seized 360 AMC V8 in a 79 Wagoneer. Even though he had been warned repeatedly about revving a cold engine, he started it up and revved the crap out of it daily when cold. It finally caught up with him on a winter day, and he spun a rod bearing, and that bearing stalled the engine and locked it solid.

Of all the engines I've spun bearings on myself, and all the customer engines I've worked on, that was the only one I ever saw locked up. Most just destroy the rod/block, crank, and bearings, but continue to run, and don't lock up. The 360 was also a rod bearing, not an main, so if a rod can lock up an engine under just the right circumstances, a main also could under the right circumstances.

The AMC engine only required a crank kit because the engine stopped immediately, the rod was still round. Like the main in the picture it only moved about 1/2 inch. New crank kit, and down the road it went until it rusted out. That is the only engine I've ever repaired with a spun bearing that didn't require at least one rod to be replaced. Unless it was a main that spun, which I have also seen, but that one ruined the block, it didn't stall and lock up, it kept running.

Hopefully the damage is fairly benign, and the damage can be repaired cheaply.
