Dave, Scott,
Why don't you see what a 3.54 rear will get you. A little longer first and maybe no need to shift to fifth gear.
I don't know about drag racing but I have convinced a few road racers to stop wasting time shifting to fifth and carry a few more rpms in fourth and concentrate on late braking while carrying a little more speed into the corners.
I am not really sure what you are trying to accomplish, just taking a guess.
