i have a 1986 camaro berlinetta 4spd-auto. i currently have 2.73 gears in it now. ive been looking arounf and guys either have 3.23, 3.42, or 3.73 i was wondering what the best one is and the pros and cons of each. im also looking at getting a limited-slip differential for it too.

 

PRO....Can't think of any advantage for a stock Berlinetta.
Con....Big Buck ($500+) upgrade with little return for you.
