The intended purpose of the car is going to make all the difference in the world as far as what gear you should run. My car is a fun weekend street car and I have a 3.50 gear. I think its a good street gear if you dont do a lot of highway driving. At 70 your going to be at about 3200 rpms with a stock height tire. The car can get to about 130 with stock height tires at 6000 rpm's.
