Thanks Bob, now that's interesting.
Is this common for some M37s ? or would this have been done by someone along the way ?
Everything else around the Engine looks the way it's supposed to in the manual.
It's amazing it all fits.
Common in the sense that once these trucks were sold as surplus, some of them received non-military Dodge/Plymouth/Chrysler Industrial small block flatheads as replacement engines (the Canadian trucks came from the factory with the larger Chrysler/DeSoto flathead, which is a different engine). Since the small blocks all shared the same basic external dimensions and mounting points regardless of their displacement, they could be swapped around fairly easily, and since Chrysler produced them from the 1930s until the 1970s, there were lots of the variations.
The military T245 version does have some unique elements, such as the bolted on oil fill tube instead of the pressed-in tube of the civilian engines, but nothing that would preclude a bolt-in swap of one of the Plymouth, Dodge, or industrial blocks.

blocks are the same for decades. only difference is some have a bolt on oil fill tube and later engines have a bypass port in the block and head for cooling instead of the external bypass hose. but early and late heads and blocks are interchangeable if you have the right plumbing. someone installed that engine at some point. M37s never came with 218. 218 is same bore as 230 with shorter stroke. they wind up a little better but have less torque. someone could have installed the 230 cranks and rods into that engine only way to know is to check the stroke.
There you go..........as said above.........the M37 only came with the T245 230 engine in US garb, and with the 251 in Canadian.....so yours is a transplant. As you can tell from this site alone........just about every engine made has been installed in an M37 at one time or another.
the ball and ball was used on countless dodge, Plymouth, Chrysler and Desoto engines. hard to tell what they came off unless they have the 3 bolt horizontal air cleaner mounting then most likely dodge military is likely.
