Poor mans lift - get yourself a set of Ford F150 torsion keys. Yes, FORD keys. They fit just fine, and only run about $26 each. Swap the keys out and you can crank up the front end to be completely level with your rear.
Spend about $50 more and get a set of coil spacers to lift the rear and crank the front keys more and you can stuff a 33 inch tire under your rig.
If you have an LT get some Z coils to add about a half to 3/4 inch more height.
If you want to know more, I did a detailed writeup of my suspension work
here.
As for body lifts, I think the smallest you can get for a NBS is a 3 inch body lift. But, as mentioned, it is lots of work to do, since you are separating the body from the chassis.
Of course, if you want to go even taller, then you will HAVE to go the route of a suspension lift kit. Usually starting around $1600 or so for a 4 inch lift and up....which is why I wen the cheap route to get about 3 inches of lift.
