the juicebox along with a good carburator upgrade (weber's the best bet) is probably the best thing you can do to squeeze life out of old 4.2L engines.
Older 4.2 engines were never really too efficent and tend to waste alot of power due to shotcomings in the design such as the shoddy stock ignition.
I installed my juicebox about a month or two ago, and after installing it, re-gapping some new spark plugs and setting the timing i found that the engine revs up alot smoother, starts a bit easier, and doesnt seem to have as many sputters when i mash on the accelerator.
Installation was pretty easy and most of the parts needed are actaully listed in the howto section of this board if you wanna assemble it yourself out of salvage parts.
