Hmm, suggestions... rebuild the 460 with some compression, 79 is 8.0:1 or less. A very mild build with some portwork and around the 9.5:1 compression mark will make very impressive power.
1 tons, Boggers, spool/weld the rear.
Good solid tow points front and rear, besides the winch, you want some nice solid clevis mounting points.
I will make no suggestions towards gearing, 5.38's will put you to the equivalent of 3.55's and 31's, but, you engine is what really makes the call on that one.
I'm currently running 4.10's with 44's, and a close ratio 6.9 T19 with the 4.02:1 first gear, sounds like an undrivable combination, but, my engine is built for big dumb low end torque, and in low range, it actually works very well.

Thats second gear, which is only 2.4...
