From his ad:
This is a "J" motor so I guess that means it actually came out of a pickup or wagon, though they only used them until 1950 � so a very short run. Meaning this is a rear block and what came in a flat nosed Willys truck (flat as in not a beak style of 1950 and on). This also means that this motor is 63hp rather than the 60hp that was in the CJ's. The motor was supposedly running when I bought it a year and a half ago, since then it has been sitting in a garage and not out in the weather
No Idea what he means by a "rear block" but the serial number indicates it came from a universal jeep to me. IT does have a front plate with both ears pointing rearward, and the right side of the plate is not very visible in the ad. You may need the adapter to install in a 3A chassis, and you won't be able to install a dual fuel/vacuum pump with that front plate. Best to just put a 3A front plate on it.
Also I don't think what I see inside the intake runners jives with a recently running engine.
Proceed with caution. It may be a fine running motor when cleaned up, or it could be a cracked piece of junk, you won't know until you examine it closely.
