I'm pretty sure if you talked to the guy someone could talk him down. It's a pretty good price, founded that the engine runs good and it is an actual aaz, but I could be wrong. Some guys are looking for stuff like this so I thought I would put it here, don't even know the guy selling it. Sounds like the fella doesn't know what he has, and could be a good thing. This engine is probably from Canada being that it is in CO, but anyone buying should be ready to face that it could be a rust bucket "all of the salt on the roads" I hope that this post helps someone find what they are looking for.
