For me? Hmm... steal Chase Bays away to redo my wiring harness. Or a spare set of crossfire TBs, new/better injectors, and a bore and sleves (for the TBs) of 500 and 1000. Or some new wheels and tires. Or custom springs, poly bushings, Z51 sway bars, good set of dampers. Or maybe brake upgrades.
Nah, I know what I would really ask for. I tanker full of 93 octane gas!
