another M-1 vs Airgap question

After reading every thread on the m1sp and the air gap I havent really found anything regarding nitrous use. Heres what I got so far:

360 .30 over with kb107s, stock rods and crank
eddy heads
519/524 lift 294 int./306 exh cam
3000k converter and 4.10 gears with a 727 auto
carb will be either a 750dp or a 770 street avenger
It will be a 100 or 125 shot on street driven 74 dart with trips to the track.

I have no preference between the air gap or the m-1sp, any tips would be greatly appreciated, thanks!
