I've always used 4.10 gears in my Mustangs, but none of them were the MT82 or 6R80 transmissions either. I found the 4.10 gears to be a little quicker out of the hole than the 3.73's that were installed into my '04 Cobra by the previous owner. As long as you have traction and enough gearing, the 4.10's have been awesome!
