A late model Z-71 is a fine truck for running 17's, maybe mid-16's at best. A 96-98 would be slower - 17's - 18's.

The high school parking lot in Whiteville , NC probably is not a hotbed for performance oriented owners that put a real tune on them. Just jack it up (preferably a body lift) as high as dad's credit card will allow, cut the cat off and run megaphone exhaust tips straight out the back.

A modest power adder would serve well -- although a higher capacity fuel pump would be needed to keep it from leaning out too much

Lol, I was talking about his z71 pals. Trust me when I say I've got my brother's '99 Z71 (5.3L) running faster than mid 16s. It's amazing what you can unleash when you know what you're doing in an ECM tune Kiss all of GM's electronic babysitters goodbye, and dial it in with a wideband, and run some good fuel

I agree however, that they most likely are stock with a body lift, some offset rims, and straight pipes. They (96-98) sound HORRIBLE at WOT with straight pipes.
