i have a 91 GT and i put 3.55's in it a few years back and i think it is the perfect gear for me. i do about 50/50 highway driving and go to the track occasionaly. I also went from and aod to t5 and with both transmissions they did good. When i went to a t5 i went with the svo heavy duty t5 which has a .63 overdrive instead of the .68 and this dropped the rpm even further its like taking off with 3.55's and having 3.27's with overdrive. I think chevrolet hit it on the head when the put in a 6 speed, there overdrive is .50. My dad has a z28 and when he is in 6th gear (he has 3.42's) his car did the same rpm when i had my 2.73's. so its kinda like you get the best of both worlds. I would like to in the future to somehow be able to install the chevrolet 6 speed in my car or just get the gearset to put in the ford 6 speed. Then i would be able to put 4.10 or 4.56's and for the freeway it would be like cruising with the 3.27's or 3.55's
