MHO, as tim said a 2A front plate, I belive the "REAR" is a typo and the seller means "RARE" (hardly). I see a "J" s/n and a pad where the oil filter would be, this would give it a casting number of 641087 and the first style w/pad, and a gear driven cam, also without the truck intake manifold and carb, and vacume advance dist it would be a 60 hp engine, not anything more.  A common 47 2A engine, nothing more than a core for rebuilding, IMO not worth $300, unless the head was removed and the pan for inspection, and if looked ok, maybe $200, still to many what if's.  Hey it ran good when removed ::), they all did ;), ran even better in 47 8-).

"J" prefix is common on early CJ2As.  The engine plate is 2A.  The head is WWII or earlier.

I agree with Bill.  Based on the crud inside the manifold ports, it is unlikely that it is a recently running engine. 

It still may be a good buy if no cracks, but maybe at $200.00

The prefix U was used on utility vehicles(wagons) My best guess on flywheel is a 97 tooth. Do you think he is trying to say it's out of an FC truck? I sure would want to see what the casting numbers on the block are and a pic of the head markings.

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.

Ran across this on craigslist do you guys think it would be able to just be bolted in or not on a cj3a?
