Thanks to all of you for the advice and expertise. Haven't made up my mind what to do with the engine, but considering my 216 (original to the truck) runs fine, it is unlikely I will undergo the necessary steps to modify my truck/this engine to fit.
Crowbar Bob- you mentioned military vehicle forums. Can you direct me to them?
I love my '52. I bought it from my grandpa, my other grandpa rebuilt my 216 (both are now gone), but this hobby is way down on my list of hobbies!
Also- I too am listed as a "new guy" which I find hilarious, as I am not a guy.
