$7K budget is tough to spend on a front dana 30 because you just want to be careful throwing that much money on mods with an axle that will likely give you trouble in the future. You could c gusset it, put in a good set of chromoly shafts, a 3" lift (evo enforcer for example) and you'd be good to run 35's comfortably off road unless you're absolutely beating the shit out of it. Regear to 4.88 and throw a locker in the rear (you wouldn't want to lock your front d30) and that would be a good set up with a light foot.
If you're even thinking about going to 37's at all in the future, take that $7K and get a fully built prorock 44 with ARB, regear the rear d44 to match the front, and you still probably have the money left over to get some good 3" springs, new shocks (like a rancho 9000xl) and front lower control arms. Shit, and maybe some takeoff 35's from someone while you save for your 37s.
