My 88 gt runs like a bear with the 2.73 gear in it, I kind of enjoy the long second gear as the power comes on when the tach crosses the 2800-3000 mark, but I can't say it doesn't feel a bit flat under the 2500 mark, How much difference is there really with a swap to 3.73 in the performance of the car, do second and third become to short? Does it really FEEL that different cause $340 for gear and rebuild kit (Canadian) and another $300 to install is a big bite so I really would like some input as to how big a deal the "FELT" effect is.
