My theory is that the over-rev damaged a spark plug and then the damaged spark plug caused some crazy detonation damaging the rod.

How would the over-rev damage a spark plug?
I could see if it had been missing a lot (the multiple miss fire codes) that the rod could have been taking a beating the whole time it was missing trying to do pulls then just randomly let go. I threw a rod on my old celica just doing 75/80 down the highway when it was full of oil.
Were you getting on it at all when it let go?
I agree that I don't really see how one over-rev could make a rod shoot threw the block 50 miles later, especially only 500rpm over-rev.
Good luck!!
