Chain cam drive 1939 thru WWII thru 1946 when the 641087 casting showed up. It was used in the 39 to 42 Willys Americar and the 41 to 45 MB jeeps. Then into early civvy production 45/46.
Some very early CJ's used the block which had the side serial pad and a much narrower pad above the water pump.
The numbers you list are not what would have been found on that series block for a factory serial. _________________ Wes K

Now your pad stamp makes sense. That's an early Willys truck L-134. It may have been a 1947/48 buyback engine. Willys bought a lot of brand new surplus Army L-134's and installed them in production civvy vehicles and power units and re-serialed them according to the vehicle type they were installed in at Willys as new engines. The T prefix on that serial represent the Willys truck which ran in production from 1947 thru 1964 using first theL134 and around 1950-51 switched to the F134. So most likely that engine left Willys in a new 1947-1949 Pickup.
The info stamped in the top row represented factory under/over sizes of bearings. That .010A means the main & rod bearings are .010 undersize. A B was used for .010 cyl bore oversized and often we would see the letters AB for both.
The 8, 8 on the clock represents 8 AUG but the year is not listed, which is common. If you could raise the old MB# from the side pad then you could narrow it down year.
If you had followed the old adage "A picture is worth a thousand words" we could have had this full answer done three post up! _________________ Wes K

Yes I agree about the pictures. It was 102 when I got home and had to
wait until I saw some downward movement before I ventured out to get
pics. Sorry.
Just to be clear, you are thinking it was an original MB block that was
surplused, had the MB # removed, then the truck number stamped
on the water pump boss?
I guess it wouldn't interest the MB guys. What about CJ2 guys? Same deal?
It came apart, no head. Has pistons, crank, oil pump and distributor, a Ford script generator with a weird mount. Almost looks aluminum. Oil fill tube, valve cover, oil pan, two different bell housing plates, a W0 carb, and a WWII fuel filter assembly, timing cover and a box of bolts and fittings.
TRUCK Serial Number Block! Who do you call????? The Truck busters!!!! _________________ Wes K

Yes. As I said my money says that was among the several BuyBacks Contracts Willys made from uncle during the 46-51 period. They were Factory new MB blocks sold during WWII to the Army as spares and Willys bought them back as New Old Stock and shoved them in their current production vehicles at the time. Ground off the right side pad MB serials and reserialed, on the pump pad using the prefix and sequence number for the new vehicle they installed it in. The undersize or oversize codes would already have been on the pump pad when those blocks were originally sold to the Army. _________________ Wes K
