Pretty sure it's around 2500. It was his mom's and she supposedly drove like a granny, so I guess shouldn't have to worry too much about abuse to the thing, unless of course she never maintained the thing. As for mechanical skills, not the greatest, but I do have a cousin who restores hotrods for a living who might be about to help out.
I live up in the North East, so not sure price wise if these are even decent.
I know a friend of mine just bought a TJ from a guy who had a rebuilt motor put in. He said where he was, a salvage yard motor was running around 1300, whereas here they're around 550. So not really sure. Was maybe going to take a run down there today, and see what kind of condition it's in. Might be something to look at.
