I have 3.31s with TKO II (.8 5th gear) and think it is about perfect. RPM is right around 26-2700 at 70-75, which is pretty good for highway cruising. But it really depends on what cam you are running, because the cam dictates in what RPM your engine will run efficiently. Once you have that figured out, match your gear ratio accordingly.

Ernesto is right about the trans gears- if you wanted to get a 5sp, I would get the TKO 600 which has the same .8 5th gear as the TKO II, but 1st gear is in the 600 is more usable than the TKO II (which is still not too bad- I think 1st is good to about 40-45 mph?)- can't remember the exact ratios of each off hand at the moment though.
