I did build one of the Lincoln/Truck Ys (302) a few years back for a 1952 F-7 fire truck, it was a parade vehicle that didn't see much use. As best as I could tell, with my CSI expertise, it had a leaky carb that over a period of time put enough gas in one cylinder to hydrolic it just a bit and bent a rod. It was ran this way till the rod finally broke and put a hole in the side of the block. Trying to find parts was not the easiest thing but on a whim I asked an old car guy that I've know since I was a kid and he had under a bench in his shop a rebuilt 317 Lincoln short block that he had bought in the early '70s from a shop that was going out of business just because it was there, he also had a flathead Cad V8 that he got at the same time, he sold it to me for what he paid $250.
I got the block into the shop, thinking it was a rebuild, and took it apart to clean and re-lube everything. After all it had been sitting for 30+ years. When I got it apart I found that everything in it was Std. and all the parts had FoMoCo stamped or cast into them. It just happened to be a factory NOS replacement engine. Long story short the engine worked fine after having to change the dizzy gear since the truck engine had a gear driven cam and the car engine used a chain. Neat old engine just like the Ford Y but everything is bigger and the only thing that seems to interchange is the oilpump. 
God Bless.
