Thats not a MB engine.
It is out of a 1941 Willys Americar. It has babbited rod bearings

While it IS an Americar engine, I don't believe it has the babbitted bearings. Earlier Americar engines are different, as the side takes the shape of the cylinders. Those Americar engines have babbitted bearings. Later Americar engines, from what I've seen, are exactly like MA or very early MB engines. But with a different serial number. Casting numbers are the same as early jeep engines.
So I believe that if the serial number was removed, it would be identical to an early jeep engine.
Edited to add: Myserial number 441-56401 Americar engine did not have babbitted bearings. Someone said they can be changed out so the other bearings can be used. Not sure if that was the case with mine, or it was assembled with "standard" bearings. The date stamped on the bottom of the block is either 10 11 41 or 11 10 41 (Can't remember which).

Hi Sam
If your engine date is Oct or Nov 41 that would make it an engine for the 1942 model year, as the manufacturers come out with the new models in the fall, usually Sept. that would make that engine a 442 and yeas. That model had insert bearings

Just to muddy the waters here is an interesting statement in a 1952 Motors Manual. And I quote.

"1935-52 All Models - Connecting rods on all models prior to Engine No. 88769 in 1942 are of the direct babbitted type. After this production engine number in 1942 and all later engines, replaceable shell type bearings are used."

I will be the first to say that I have found mistakes in Motors Manuals before as they are a third party publication and sometimes they just got bad information and i am sure other unexplained reasons exist.

This is a statement that fly's it the face of first hand accounts of a number of people just on the "G" alone. I personally suspect that any engine production number change to shell bearings was much earlier. But that's just my guess.

Roger
