They have not made 'plain 3's' in a long time. 3A's (which are basically a long version of a 5) and 5's are discontinued.

Re: difference in drives
Cig 39, 4 or 5 has a prop shaft height 5.5" higher than a 3 or a 3A. I have run 850 hp thru small shaft fours and did fine. However, I am sure that if I had wanted to I could have went out and broken one by being stupid. New parts for the 3 and 4 are getting a little tough to find. 5 is ok. Seems like the gear selections are the first to dry up.
