4.10s are good with an auto and 3.73 with a manny. a tune and some good tires will get you well into the high 13s

4.10 is definatly the best gear you could run for an auto. What kind of exhaust did you buy? Catback? Midpipe? You might see high 13's with a cold air, midpipe/catback, and 4.10's if you have good tires, what rubbers on that thing? If that's not enough oomph get yourself a tuner like the diablosport or sct or step up the throttle body/plenum size.

I ran a 4.30 gear in my 2v. If I ever get another 2v that would be the gear. I dont know about a auto though, this was a 5 speed. 2v's need as much help as they can get. I got beat by a 300 with a hemi that had 4 guys in it. I do miss it though. Fun car
