2003 Chevrolet C-5 Corvette
402 ci, Supercharged (air to water IC)
E-85 or Race Fuel
Clear Title
This custom show and streetcar is basically all new. It began as a frame-up build in 2014 and was completed in 2016, practically nothing was untouched with the goal of creating a unique, one-of-a-kind C-5 Corvette (2003 model year) that could win at car shows.
Practically every component is custom, with each built by a shop that specializes in whatever component was being upgraded. The vehicle was meticulously hand-assembled. Some parts are one of a kind for which many hours of R&D and fabrication were invested. For example, an aluminum fuel cell was fabricated to fit in the stock C-5 driver side fuel tank area so the stock fuel fill can be used, allowing room underneath to a gravity feed fuel pump. The engine was built one piece at a time, from the short block to the heads. The short block is new with an iron 402 LSX bowtie stroker that was modified for ½ inch studs and more by Weston Machine and built by Roche Racing Engines. The power glide transmission was custom built from torque tube and a carbon-fiber driveshaft connects to a Ford 9” rear end with custom axles and more. The suspension was modified to include Farks lower A-Arms, AFCO coil-overs with front limiters. The manual steering was designed and fabricated to match the OEM power rack (it requires almost no adjustments for bump steer). The intake was custom built by Hogan’s Racing Manifolds, the heads were built and hand ported by total Engine Airflow with titanium and Inconel valves, etc. The list goes on and on right down to brand new WELD RT-S rims in the rear and modified with Champion Beadlock and brand new MT radials, while the front has new Weld Alumastar rims with new radial tires and polished Weld center caps with Champion matching lug nuts.
No corners were cut from the nose to the rear of the car, including extensive electronics with a Haltech 2500 ECU including GPS, data logger, custom fit into the dash with a leather surround.
The car is running and this build costs well over $200,000.00
Since completing the build a few final tweaks to the suspension, rear sway bar, new rear rotors, wheels, etc. I have taken it to one car show and won, but I have never raced it.
I cannot tell you the power it is making at present, since we have not had it on a dyno.
It does not have A/C, heater, but does have power windows, power door locks, everything based on an original corvette.
My health has made me not race this car as well as respect for the beauty.
