Gains to be had going with 3.73s?

[brickonwheels]

I currently am running 3.42s and am running 12.4@109ish with my LE1 H/C setup. I am running a 3600 stall and will be spraying on top of it. What kind of gains might I see if I went to 3.73s?

you will 60' faster for sure as long as traction is there...i would go to 3.73s then dial in the car on 26" tire on motor passes and go to 27'' or 28'' tire when sprayin
