Gear ratio & tire size

I'm trying to install a LS1 and a 4L60E trans in my '33 Ford and I need to know the stock tire size and gear ratio in a '99 Camaro LS1 with the auto trans. Can anyone help with that information.

Re: Gear ratio & tire size

Tire diameter is 25.66. A4's came with either 2.73 or 3.23 rear gears. 4L60E internal ratios are 1 - 3.06, 2 - 1.62, 3 - 1.00, 4 - 0.70. Is that what you wanted?
