hmmm, not much potential there, but, if you insist on hookin it up at least alil...
1. im guessing its like a 4.3liter v6 or something, hmm, really cant do much with that........ its not like a small block chevy when you can just do cam and heads and hit 450hp easily; if you have like $2,000 or so you can put a turbo on it, like the ones they put on a grand national/regals, its all gm so alot of stuff could interchange who knows, lol.
2. That stock stance is ugly as sin, so, you can either A. lower it and make it a spanish cruiser or B. lift it up; not much reason to lift it, cause you w/o much torque you cant do alot of offroad stuff. So id say lower it like 3-4 inches.
3. get that thing a maaco, plaine old white=ugly
do 2 of those 3 things, and your all good, IMO its a waste its an old jimmy, id say just borrow that beast your sisters got
