Sounds good i think you'll do well with the 4.11's who's building it for you?..as far as traction throw a set of drag shocks on the car,i'm running the Summit brand on my duster they're cheap price wise,and do help my car 60's in the 1.40's with nothing more then the shocks,h.d. leaf springs and a pinion snubber..as for the m/ts you'll need to experiment with them to see what pressure your car likes..mine hooks great at 15 psi's..
