tell me your opinion on my set up

[meatwagon83]

so im in the planning stages of my truck, heres my plan thus far, 8.1 4l80e 205 dana 60 front dana 70 rear, 3.73 gears 34x 9.50 tires,

do you think its going to be enough gear? or will it be a pig, motor in final form will have about 600 ft lbs, and its all going to be in my crew cab dually, (hence the skinny tires!)
