Torque box question

I'll probably stay with the 340, definitely sticking with 4spd. No gears selected yet, drag radials are 390x40x17 m and h. Do you think torque boxes are overkill? This is a Notchback. It's only $250ish for all 4 boxes, and I like doing the work
Boxes can't hurt, so long as they are installed properly. Unless your car is rare or limited production, I don't see why not.
