Any tips for 4WD launches?`
I think i have a decently solid setup, just rebuilt my front axle with a few upgrades, welded tubes, bigger u-bolt yoke.
My setup is LS1 Built 60E NP208 case 9.25 axle and dana 44 front. I feel the 60E is built right, NP208 is a low miles case but still chain driven, my chrysler 9.25 axle is big, but no real upgrades other then new bearings, dana 44's are said to be strong, wondering what issues 1/2 tons trucks run into with 400-500 rwhp running 1/4 in 4wd

I think that being lifted keeping the weight from transferring too much would be a big one. Can you put some sort of limiting strap around the front axle? You will also want to think about traction bars to prevent the leaf springs from wrapping around the axle (not sure that the correct term is) and causing wheel hop. Outside of that I think bring the converter to about 2500 (just a guess as I don't have the same one) and then drop the hammer when you leave the line.
With everything you have going on in that truck I'm surprised you don't have a cam. It would sure love it. I would think something very close to mine would be awesome. give you more top end pull, and more torque where the converter flashes to. In my truck on the stock converter it was worth .5, I think with your converter that difference would only be bigger.

I think it will launch just fine in 4x4. See if you can get somebody to video the launch. Check to see if the front wheels jump side to side, or if it bunny hops. If it does, just address those issues as they reveal themselves.
