specifically superchargers, headers, exhaust, etc. trying to increase horsepower as much as possible... it has a thm700r4 tranny with a 350 5.7L engine. i've checked out lmctruck but they seem more intent on restoration than upgrading.
note: it's a 4x2, not 4x4.
they didn't start fuel injection in suburbans until 87.
