I have a friend that has all the books, so I have never had to buy one. Anyway, he has been rather busy with some other things of late and I find myself in the dark to answer these questions.

There are some great reference materials you can locate and purchase through vendors on this site. Go check them out. I know I am going to soon.
CMA suffix

CMA is a '74 Impala/Caprice 350 2bbl with THM350 trans.

Not a corvette engine.

The CMA suffix was used twice. First in 1972 for a 307 tur hydro, Calif - 130hp in the A F X bodies. Again in 1974 for a 350 tur hydro trans in the A B F X bodies. Both were two barrel carb engines.
