I think you guys are right, with 31" tires a 4.10 might not be too much gearing. Need to know exactly where and what you bought and for how much! TXIGGY
Very much interested in what you have.

As for the BBK throttle body. I think stock is 75mm and it is 80mm. I did stick badly until I added a second spring to it, it was also needed as safety for NOS. I feel I wasted money on all my bolt-ons except for NOS, Hypertech, and K&N. Woulded recommend anything else I've done so far!
Thanks guys,
Oh ran 13.66 last night, hopefully because of weather, I think I should be between 13.2-13.3
