If you will be doing commuting, then a stock 3.64 or 3.9:1 are fine. If you race, then a 4.45 is better.

most 5 spd overdrive conversion opt for the 3.90 to get the acceleration without the penalty of increase rpms. But if you have a motor that can pull a 3.64 then that may be a good option too. Anything bigger or smaller becomes too specialized and not a good compromise for a daily driver. Differentials are easy to swap and cheap, so you in a sense you can have your cake and eat it too.

Works well with lots of off the line go and still cruises at a slower rpm then a 4spd 3:64.

In mountains, windy little roads, 4.10 or higher if you can get it.

All freeways at 80 plus mph all the time, 3.64 is good. 3.90 is a great compromise.

but i wanted the ability to run on the freeway with a 5speed tranny.

Nobody there has a gas pedal. These people don't even realize they don't have a speed limit. Go with the highest ratio you can find, it will still be taller in fifth than it used to be in fourth.

5-speed O.D. with 3.90 LSD, and it's an excellent compromise -- more torque down low and reasonably quiet for highway cruising.
