Even will the guesstimated 550rwhp won't the T/C be a big help and keep the spinning under control and is it worth it to invest in the 3.90 gears? Do ya'll think you could stay in 3rd gear or would you think you would have to shift that extra time running the quarter? Would that extra shift be worth it if your were trying for a good time? I know the 3.90's over the 3.45's would feel much stronger but would it actually help the time in the 1/4?
