For all these statistics about CSA industry postwar, remember that any data based off the US Census of 1870 is going to be colored by the fact that the CSA was utterly destroyed by the Civil War, including its heavy industry. A CSA that wins the war will have significantly less destruction than OTL, and therefore more economic strength. Anything using postwar US figures is going to tremendously underestimate the CSA.
That said, the CSA would not be a very great industrial power, since their whole society is oriented against industrial development. A good third of their population is completely unavailable as a domestic market, at least until they abolish slavery. EVen then, they are a fundamentally agricultural economy that has a large part of its population treated as second-class citizens, and thus need to be kept down with force. Their central government, or lack thereof, will cripple them as well. They do not have very good growth prospects. Whatever they start out as, they will start to slide eventually.
