I am making a Super A hybrid using a lot of 140 parts. The 140 block is different. The crankshaft is different. The sleeves are different.
What I can tell about the 140 block is that it has mounting holes for a water pump and fan assembly that the Super A blocks don't have. The rockshaft lift arms look identical except that the rockshaft arm on the 140 that had a helper spring had a larger diameter hole to accommodate the helper spring than the Super A had. The thread diameter for some of the mounting brackets on the side of the bellhousing and transmission is larger on the 140 than Super A.
The crank pulley on a 140 is different than a Super A. The crank is different from a 140 and a Super A. A 140 crank can be used for a Super A, but a Super A crank cannot be used for a 140. The 140 crank is threaded, if you cut the threaded part off it can be used for a Super A pulley. I have been scolded for doing that to the crank, but it worked. The cam is identical. The 140 fuel tank will mount on a Super A, but is taller.

It is also very apparent that these folks are getting a lot of very poor and often very dangerous advice fro
