An 8 3/4 that is set up properly is more than enough for an A body. Remember, 440 E and B bodied cars came with them if they were automatics, --- and they were heavier cars. However, if your running a transbrake, a stick shift with a strong clutch, or 10'' slicks at the track taking off on the sticky stuff, then consider a Dana. [opinion]
