Hello all!

I received a 440 for free in a trade. 77 block, low compression, cast crank, all stock (even had the original nylon single timing gear, chain was super loose). It did have the thin metal head gaskets though. From my quick measurements, stock bore, no cylinder ridge.
The engine came out of a mud truck, big headers made out of fence pipe, etc. Pretty entertaining.

Anyway, I was hoping to tear it down, re-ring and new bearings then possibly use it for a project I have.

This is what I found. It looks like a bullet hole? in the oil pan and the sludge in the pan indicating bearings run without oil for a short time. No bullet or associated damage could be found.

The engine spins freely by hand, the rods ends are not discolored.

I usually overthink things, so now I am stuck between "re-ring it, new bearing install and send it" and "take it to a machine shop and have them check/machine it all"

What are your opinions?

Thanks,
