700HP 2002 Corvette Z06 - Exposed Myth

Yes, 700-rwhp street cars exist--we caught one!

The 427's power is channeled through the Z06's stock six-speed trans (with a heavy-duty clutch, of course), a hardened driveshaft, hardened halfshafts, and out to the Hoosier-shod CCW 16-inch racing wheels. A set of racing "skinnies" is up front.

Suspension and chassis mods are few: HAL QA1 adjustable shocks, high-performance brake pads, and a transmission brace. Star Chassis also stitched a six-point rollcage into the car's frame. Outwardly, the visual accents include a Motor City Molds hood, an RKSport spoiler, and BPP headlamps.

Not surprisingly, this Vette has garnered more than a couple of show awards, but its real forte is the dragstrip, where a good launch helps shove the car down the track in less than 10 seconds. Such performance is a balancing act for Leake, who says maintaining the car's streetability was a goal from the project's start. "When you're running 9s, it's a fine line between street car and all-out race car," he says. "So far, so good."

A fine line, yes--but also the stuff that generates a reputation of mythical proportion.
