your going to want to go with 4.10 or even 4.30
i had 4.10's and swapped them for 3.73's because i installed a kenne bell. i miss the 4.10's, it was more fun to drive; however, 435 rwtq at 2600 rpm and 4.10's = 0 traction... 3.73's are alot more tame with my setup. centri's build boost higher in the rpm range, so if you have a set of 3.73 gears its going to take you longer to get into your power band.
