The Spruce Green Bonneville retained much of its assembly-line amenities including the 12-disc CD changer, power windows and door locks, cruise control, keyless entry and alarm system. Confident of the car's ability, Cook played the radio during each run listening to KSALT 1610-AM, the voice of Speedweek.
The stock parts were joined with a few "race ready" revisions:
- A six-corner roll bar attached to the roof line and chassis, creating a roll cage to provide additional roof crush resistance for the driver in the event of a crash
- Jaz Products aluminum racing seats and covers in place of Bonneville's traditional bucket seats
- A Deist parachute, competition seat belts and fire protection system
- Custom-built "Intro" wheels, body lowered four-inches to reduce drag and lift
- Specially prepared transmission by Hydramatic Motorsports
The Bonneville's supercharged 3.8 liter V-6 engine, which uses a Kenne- Bell supercharger, was re-worked by Richard Lee of Lee Performance Products (LPP) and produced in excess of 600hp @ 6000rpm. Ported and polished cylinder heads have been re-worked by Morgan Engineering to substantially increase the power potential of the cylinder head. A special crank and rod preparation with balancing was performed by Evans Speed Equipment. Doug's Headers fabricated the custom exhaust system with thermal barrier coating applied by Engineered Applications. A LPP fabricated intercooler was added to the vehicle to pass cooler air from the supercharger to the engine. The 4T65E GM Powertrain transaxle was enhanced by Hydramatic Motorsports to run over 200 mph and the final drive ratio was changed to 2.56 from 2.93.
