If the 91GT was auto, they are 3.08 gears. If it was a stick car, 2.73 gears. I like the 4.10's I have with my t5. Most people will tell you to go with 3.73's. They will give you the best seat of the pants feel, while getting decent mileage. The 3.55's won't give you the feel that the 3.73's will, but you'll get a little better mileage. My car is a hot rod I don't care about gas mileage. That's why I have 4.10's. I am even thinking of going to a 4.30 or 4.56 gear. Ulitmately, your gear selection is based on your engine's power band. Since you are still going to drive the car on the street, I suggest 3.73 gears. What size tire are you planning on using?

I just read your other post about the engine again. I see you are using the AOD transmission. Since that's the case, I wouldn't even hesitate to put 4.10's in that car.
