On street tires there won't be as much of a difference than on slicks. A stock AOD car will most likely 2.1-2.2 60' because you can't launch the car. A 5 speed car on slicks can go 1.5x 60' if you can get it to dead hook launching at 6000 rpm, I've done it before, thats .5-.7 seconds right there, not to mention the car will accelerate faster because of the steeper gear ratios and less drivetrain loss with the 5 speed over the auto. I think it will be a full second faster on slicks.
