That being said... There are two different 239s. (as Ford loves to confuse everyone)
If it is the original block to the car, you likely have the Dearborn version of the 239. It was made in '54 only and installed in the '54 cars and early '54 trucks. It has cam journals that are 1/8" larger in diameter, different cam bearings, a 13-tooth distributor gear, slightly different cooling passages in the block/heads, different head gaskets, and "small" intake ports. It also uses an upside-down fuel pump.
The Cleveland 239 was made in '54 & early '55. It was produced for trucks starting in mid '54 production & continuing into early '55. It was replaced in mid '55 by the 272 in trucks, although FoMoCo continued to use the same glove box tag engine code letter & identifier. This engine is essentially the same as all later Y blocks...same small cam journals, a 14-tooth distributor gear, and so on. However it does still have the "small" intake ports on the heads.
So there's a little bit of info. While Y-Blocks are very cool, they are definitely a beast all their own and take quite a bit of research and trial & error to build...
