3.08 to 3.73, how much difference?
 

Hey guys, I just bought a turbo coupe rear with 3.73 gears and was just wondering how much difference in the 1/4 it's going to make. As you can see from the signature, I'm hitting 14.6 at 94. My car is heavy!! 3590 is daily driving weight and the weight I ran at the track. I have a feeling the gears would help me slightly more than a mustang because of the more weight, what do you guys think, I may be wrong, but reguardless, how much difference should I expect?

The "Quarter Jr." software program says about 3/10 assuming you have traction.
