UPDATE: **Sold** Was $800.
I wonder if this was an industrial engine.
“Flathead 4 cylinder Willy’s Jeep Engine, WW2 vintage. This engine starts on its own with just being choked (no other starting aids needed). Oil pressure is good, and there are no knocks, or crankshaft “Chuggle”.
The compression of this engine is 75-90 psi, and it can still carry a load (it was the powerplant for a functioning welder). There are traces of olive drab paints on parts of the engine, and the timing cover has the rivet in it that wartime Willy’s had. The serial number of the engine is MB546645. The additional numbers on the engine block are 1-11, 638632W2 A, and NI-CR N2 ( designators for a nickel-chromium iron block alloy; for those of you who don’t know, this hardened block material is one of the reasons that these engine run forever).
I believe that this engine could be dropped in and ran as-is for quite some time, or it would be an easy one to freshen-up with piston rings and a valve job. I prefer cash as method of payment. The engine is currently palletized, and is available for local pick up, or shipping arranged by the purchaser. These engines are not getting any easier to find, so even if you have a good engine in your Jeep, it might not be a bad idea to have a spare.”
