Default Which gear for my turbo car

Well I have everything together and dyno tuned to 602 rwhp and 712 tq on 14lbs and thru a 4l80e. The car currently has a 3.73 (12bolt)gear in it.want to try and keep my shift points below 6700. What gear are some of you hi 9 sec and 10 sec guys running. this is my first tune and i am going to more boost soon so prob tac on another 100+hp for the track with race fuel. Any info would be appreciated. Im currently using a 28in tire and a 3600 yank verter in it. 408 with a ptk t-76 turbo kit on it. Ive built mainly a street/strip car. I like to drive it.

Your 3.73 gears will do it with a 28" tall tire, but for a turbo you may be faster with a set of 3.23 or 350 gears. Bob
