As far as I ever knew it was the Chrysler 217 or the 230. I don't know my flatheads very well but I don't think a Jeep engine will work.

What engines are compatible with a 1951 Plymouth?
I have a 232 from a Jeep

The 6 cyl flathead was used in Plymouths since the early 1930's. A 6 flathead from Dodge, DeSoto, or Chrysler should bolt in also. Of course you can adapt for other engines.

Do you think a 232 from a Jeep will be adaptable if I make a custom bracket

I see no reason why the AMC/Jeep 232/258 wouldn't work assuming your oil pan clears the steering linkage and crossmember. Too; assuming you're running a matching tranny; make sure that things clear there as well.............if they do, you're home free since things like exhaust, cooling, throttle linkage, etc. are (relatively) minor to sort out.

You would have to find or make an adapter to fit. FYI. A 230 Plymouth flathead was about 30" OAL including fan. However a 265 was about 33". They are different lengths for different cu. in. I believe that yours was equipped with a 217 cu. in. (1942-1953+) 1954 came with230 that Dodge already had.
