Isn't 'Cuda a model, not a nickname?

69 440 'Cuda was not the only 'cuda that year. 69 was the first year but the 'cuda package also came with a 340 or a 383.

The 340 'cuda will have A56 on the fender tag and the 383 version will have A57. These cars are not to be confused with the formula S which was also available but had many differing options.
