Before you do anything, i would work on the suspention & get those ETs down in the mid 12s where they should be with that 108 trap speed, i've gone 12.4s at 108, i've seen 12.2s at 108, theres a good 3/4 second in that car, those 3.71s aren't the best gear for a SB thats modded, at least a 4.30, or even a 4.56, you can keep adding HP, but if the car doesn't 60ft., its all a waiste, just my opinion.
