While I'm no fan of full time 4x4, a 203 doesn't scare me. A dana 44 front, 33" tires a 440 and a 4 speed does though. If you really are going to try 4 wheel burn outs, start sourcing a dana 60 front. With stock size tires, a tired 440 and 4 speed, any time I got offroad, the 44 front was shelling parts. Everything was replaced with new and still broke.......

I have a dana 60 front with a lockrite, and all stock components that are 35 years old, and a much better running 440. I've never had it opened up since I put it in the truck 9 years ago and its been beat a lot.
