7xl on 14 cells too little? (torque wise)

[Superbasher]

Ive had another look around (here we go again lol) and what i thought is: the maxx wil already have GA bulkheads on it, so couldnt i just use the GA diff cases, and get the maxximiser diffs? (i want to save money, and im not going to be jumping lots, nor will i jump it high. would it still be fairly tough with that setup?
thank you all for all your help! :)
