6V92 Question

[NJT5047]

Most likely if there's no turbo, it's been removed.  The turbo might be mounted low on either end of the engine, or high mounted on the blower,  The blower high mount is correct for an MCI.  The owner either doesn't have a clue, or he's trying to hook a sucker.  Whatever, the picture isn't good.   As TomC sez, OTR V92 series had turbos.   
Stationary engines (generators or oil field pump motors) would be the only thing in a V92 non-turbo.  And it ain't that. 
Another way to rule the engine out is to dig through the layers of paint...if you find 'Alpine Green' as the base color, walk away.   
The transmission is very likely an Allison HT740, 4 speed.  But that oughta be verified too. 
If you cannot run the engine and verify the condition, I'd walk.  If it's been sitting around for years, it really should be freshened up before trying to use it.  It isn't worth "freshening up"....
Not enough info to make a decision...yet.

Seller must be responsible for providing accurate and timely info....if he is secure with what he is selling.  Too many unswered questions for my taste; FWIW.  (HB of CJ)

Second hand info, for what its worth. Fire truck engines have the governor set to about 2500 rpm, and when they get rid of them they are pretty much cooked.

  I would second this. Fire depts dont get rid of good working equipment. Once they start having issues with stuff they pass it downstream to smaller fire units until no one wants it. There are tons of MC9's for sale right now, many at scrap price and less and most ride and drive. You could quite easily find a less than pretty one with good running gear, take what you want, and either give away whats left or possibly even get someone to come and get it and pay you for the trouble.

  Unless your mechanically inclined and can adequately verify what your looking at as well as its condition, I would stay away from it. Even then, if you cant start it or otherwise test it, dont pay much more than scrap/core price for it.
