I think it is just a different trim package, seats and what not.

those straight six motors wether its a 4.2 carb or a 4.0l, you cant kill them if it was well maintained. they seem to run forever

The 4.2 is a good motor if well cared for.
Yes, it sounds fabulous with a Flowmaster 40 series.
Yes, a Rough Country 4" lift kit can be had for less than $600.
Yes, you will need 4" springs to clear 33's.

I would recommend staying away from lift shackels larger than 1".
I have them and an considering going to 5/8" boomerangs when I get my springs.
They do strange things to the steering geometry.
