in a 5 speed aplication you could go as low as you wanted as in a 3.50 low gear and evenly space out the rest of the ratio's to help with the rpm drop off on the gear changes.in the 4 speed it would be like a 3.0-3.2 low gear an then second would be in the 2.0-1.9 range and there would be a bigger drop off than there would with a 5 speed.i do know that a ss/ah stick team tested with 4speeds and 5speeds and these were the results that they came up with,the car was faster with the 5 speed and the powerband was more managable because it didn't have to be as wide as with the 4speed.
