???? Are you talking about the thread starter and his '70 GMC?, or his z-71 arch enemies?
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
