Is a pistol grip shifter a good choice for power shifting/drag racing?

Id say no, but I never shifted one either. Physics will prove a shorter lever is faster, and that pistol grip would make a better E-brake handle than a shifter. The old ball is great, 360 degree access and a smooth handle . I had a T handle on 4 speed once and found I used the shaft more than the handle to shift with quickly, especially pulling it towards me.
