Ia49, I've been trying to make the same decision for over a year now and for me I am down to two choices. 1) go with a car 3 speed to keep the 3 on the tree, and a 3.73 rear. I do most of my driveing around town so I like a slow 1st & reverse and I can be happy with 55 or so top speed. 2) If you don't care about the shifter go with a t 5, much more versitale, I still think the 3.73 is about right.
Power wise with the 216 I would not go any lower than 3.50 range with the rear.
