Good Morning, I just purchased an M38 and I would like some help identifying these blocks. From other posts and forums I found some identification pictures that have provided some guidance. See below pictures:
Engine #1:
Is this Willys MB Late War?
Engine #2:
Is this a late M38?
See one of my references below.
I can get more information if needed. I'm trying to choose what block to go for in the repair of my new M38 and would like to make a good decision.
Thanks,
Engine ID

Re: Engine ID
Engine #1 I see a faint 6 before the 4T, 4T was the Willys Pickup truck made from the 50’s into the mid 60’s so definitely post war civilian.
Engine #2 has the long water block flat so also post war. Serial number stamping doesn’t match anything that looks familiar, I’ve also never seen that head. It’s got a 6 - 48 casting date so possibly some sort of industrial head. What’s the casting number on the side of the block? It could be a CJ2A block that was decked and restamped.
Neither is an M38 block.

Re: Engine ID
Both engines are the post war casting used from early 1946 into the early 50's

Re: Engine ID
There is no added value on which one to use for the M38 right in your opinion? or can I say one could have a closer physical appearance to the correct one over the other?
Let me know your thoughts.
Thanks,

Re: Engine ID
Neither is more correct. If possible I’d get a machine shop to check for cracks, cylinder wear, valve seating, etc. and use the block in better condition.
