Your goals are simple on these, no voodoo for that.
Honestly, you can do it with a 5.3 too, it'll just be a little easier with the extra cubes. A 6.0 with a cam kit, set of longtubes, and a pro tune should have no problem getting those ponies. If you spend the $ for a good convertor,you'll be able to feel all of them.

A cam (shelf grind of custom doesn't matter) with some hardened pushrods and good springs is $350-450. Grab a good timing kit, and an oil pump if its got higher miles, again usually under $200.

The 3 most expensive things are also the most important IMO; good headers can be up to ~$650 but your leaving 15+hp there at least. You can get by with cast manifolds, but the headers really do make a difference.

The tune can be expensive (a dyno tune w/ road tune), but it alone nets a good chunk of power, and is crucial to having a good driving truck. Its also a valuable relationship to have with your tuner for when your power goals grow and change, in many cases requiring more..and more complicated, tuning. ~$350-500

Lastly, the convertor. While it doesn't make power (and sometimes appears to steal a few ponies on the dyno), its also what changes a civilian truck into a performance vehicle. It will take the increased power level and better and holding under WOT shifts and downshifts. The stall you choose will also be important into pairing the gearing and cam so that your spending time with the engine in the sweet spot and not wasting effort. Its also the thing that lets you launch the truck. Don't cringe, they range ~$550-1200
