Like Dwight said, the motor, transmission, tires and wheel size are going to make a difference. Also what you want the car to do. I have 3:56 gears in my Coupe but they cut the top speed down. My NASCAR Cobra has 3:91s and it accelerates very well up to just over 100 MPH but the top end is low. I had 3:27 gears in one Cobra replica but could never use 5th gear as I had a racing engine and it wouldn't run at the RPM in 5th gear to keep the engine going well. So it all amounts to all of the above and what you want to do with the car.
