I had 3.73's and switched to 4.10's. My Fox is an AOD. I saw no difference in track times , mph and very little difference in rpm. There was no noticeable seat of the pants feel. What made a huge difference was a 3500 stall converter. It really woke the car up.

89 LX Notch: Floo-Tek 5.0X heads, GT-40 intake, B-303 cam, Dynamic 3800 converter, 4.10:1 gears & lots of suspension work. 12.50 @ 106.42 MPH.
