i think 90% of the benefit of 4wd is in the 60 foot. when i tried in 2wd, all i did was spin off the line. i let off, spun again, let off, spun again.. etc. launching in 4wd was zero spin aroun 15-20 psi. i wanted to launch harder, but the stock turbo wasnt happy already!
what do you do with your truck? do you haul ? i am willing to bet suspension work with slicks will net similar results with far less dollars than a conversion.not to mention the conversion will add weight and rotating mass which will urt top speed...
I'm in a similar situation (and running similar ETs), but you should be less nose-heavy than my truck just by wheelbase alone. I tried Caltracs, which eliminated wheel hop and helped it hook better, but I still need more traction than I can get with my big E-rated dually tires. After I install my new torque converter, I'll probably try a pass on slicks.
