The chassis and suspension were next. Adams painted the frame satin black and installed Shark Bite aluminum upper A-arms, QA1 adjustable coilovers, and a Vette Brakes and Products sway bar. The rear, meanwhile, was upgraded with a VBP modified transverse spring and Vansteel offset trailing arms.

Adams then mated the body back onto its frame and continued the drivetrain installation, bolting up a TCI torque converter with a 2,500-stall speed, a GM 4L80E computer-controlled trans, and a TCI stand-alone management system. A modified stock driveshaft connects the trans to a rebuilt GM Posi rearend with heavy-duty yokes and 3.55 gears. Braking power is dele-gated to factory discs with drilled and slotted 11.8-inch rotors, while 18-inch Boyd Coddington Junkyard Dog wheels wrapped in BFG KDW-2 rubber keep the Vette firmly planted at all four corners.

Adams' interior restoration includes factory thrones recovered with OE-style material, a stock steering wheel, and reproduction cut-pile carpet. Amenities include Auto Meter Phantom gauges, an Alpine head unit, Rockford Fosgate amps and subwoofer, and MB Quart speakers.

Comfort tweaks aside, the most noteworthy aspect of this ZL1 Vette's amazing story is its ProCharger F-1R blower. "I was confident the ZL1 could handle 600 hp on its own, but my goal was 800 hp," Adams says. "I wanted the ultimate shark that would perform in every area, have all the creature comforts of a modern car, run on pump gas, and still supersede the power output of the legendary ZL1. But, fitting the F-1R supercharger in the stock engine bay without cutting or modifying anything posed a few problems. I had to spend many weeks modifying the supercharger's hat, and fabricating brackets and piping.

"I also intended to run an intercooler, but the C3s are limited on space up front. As an alternative, I went with a Snow Boost Cooler methanol-injection unit to control detonation. It's computer-controlled, begins spray at 4 psi, and hits full output at 15 psi. I utilized the stock windshield-washer tank for this application."

Adams also modified a donor L88 hood by removing the airbox and molding an electric vent door into the underside of the cowl. It opens when the electric fans are activated and helps reduce engine heat. The hood-support rail was also reworked to allow clearance for the massive F-1R.

Finishing the car in time for this year's YearOne Experience proved to be even more of a challenge than Adams anticipated. "There were numerous fitment issues that came with the mods, so it wasn't just a matter of bolting stuff back together," he says. "I went into hibernation almost every weekend for several months to meet my deadline. I even had to take two weeks off from work right before the Experience to finish everything. I cranked the car for the first time Wednesday night before the event, and we left for the show the very next morning. All the hard work paid off, as I was able to take First Place, with many positive reviews."

His hard work completed, Adams has every reason to feel proud of what he believes is the only supercharged ZL1 Corvette in the world, a supercar that drew its inspiration from his very first time in his father's Vette. "I plan on using the car for shows, Corvette club functions, cruise-ins, and leisurely drives," Adams says. "I also plan on taking it to the track on occasion. It's my dream come true."
