I think the engine is pretty much done :/Yuck!!! Stick a score down the hole and see what other bits and pieces you may have to fish out. :- (
I am in the Navy so I don't have that kind of time, I found a decent mileage replacement but ill have to pay someone to put it in which sucks! If I had the time I could put it in myself but sadly I don't.That really is too bad. Now what is your plan? Unload? Swap low mileage replacement? Rebuild (no idea if can be done with whatever damage you may have)??
Here is a V10 rebuild (yes I know you have a V8 but it is the "in and out" that is interesting here to me). Anything is possible.
