Well based on your ad, there are too many unknowns.. I looked up Jasper and they don't sell slant 6's on their website. Also, I'm guessing the owner bought a rebuilt short or long block (unknown) from Jasper and installed it themselves or had Jasper install it. But the engine looks more crusty than my 50 year old engine, but the papers in your photo look brand new... Did Jasper sell reman engines 50 years ago? I don't know... Also you dont mention what the miles or the trans is, auto on the floor, auto on the column, 3 speed manual, etc... And also what the previous poster stated, what comes with the prices is confusing... I'm not saying you're trying to pull anything sneaky, I'm just trying to get a grip on exactly what's being sold. :steering:
