How much would you pay for an MKVII?

Yeah, 5.0 engiones last forever and a couple of days if you don't starve 'em of oil or run em hot. Excluding racing, lol.
Hell, my '92 F150 with a 5.0 had close to 300,000 on the engine, ran great till the day she went to car heaven.
Of course, it'd had a new timing set, intake, oil pan, and front cover gaskets, fuel pumps, and some other little piddly mechanical stuff replaced in the 10 years I owned it. Ran great though. If I knew for certain the cylinders weren't egg shaped and past the point of getting by without boring, I'd have kept the bottom end for future use. As it is, I have the previously-mentioned Stanger HO short block on my stand..car allegedly had 60K on it when it was pulled, so we'll see.
So I'd say yes, that engine may have only 100K on it...which isn't very much to worry about it, as long as the thing had proper oil changes and the like. Have someone knowledgeable measure the cylinders with a mic (i know there's a proper name for the tool-can't recall it right this second lol) and that will tell you whether it needs any machining or boring.
The pistons are stockers, as you can no doubt tell from the casting marks, so we know it's a factory bore.
And you also get an HO EEC with the car, lol. It also should have an H pipe like the stangs use, unless you've a better one, or someone has cut the cats from it...if not, might make a few bucks off of the cats to a recycler if you've no use for the H pipe.
If you can still see cross-hatching in the cylinders, it's a pretty good block, at least in the cylinder wall area.
'Luck!
