I had 4.10's in my turbo'd 91 GT convertible. It was a heavy car with a built AOD, and I'm not gonna lie to you and tell you it wasn't hella fun on the street! It was a freakin' blast to drive around, but it revved so quickly it wasn't really letting the turbo work. I switched to 3.55's and went quicker and faster in the 1/8th with the 3.55's because they were letting the motor load and the turbo work. Plus wheelspin wasn't as big an issue, but the 4.10's were loads of fun in the heavy car.
