Trapping 120 might just be possible with the setup in my sig plus a 150 shot and more bolt ons in the near future. Im aiming for mid-high 11's..maybe i should go with a 4.30?

you want a track truck? then dont fear the gear go with 4:56 you'll love it on the street, i ran a 4:88 gear on a 28" tire, let it eat, you wont even be near running out of gear unless youre racing a mile or so, i went on a 150 hit of nitrous on a 408 went 10.49 at 132 and slipping off the line !

im aiming towards 11.5's..if ur doing mid 10's at 132 and still have gear left, then i should be more then fine..from the way everyone talks about 4.56's, i think im gunna go that route.
