I saw this car at SEMA back in 2008. It was built by Year One and Gillette Evernham Motorsports in conjunction with Bill Goldberg and then sold at Barrett-Jackson to benefit the Darrell Gwynn Foundation, which works to help cure spinal cord injuries. The car started life as a 1970 Plymouth Satellite but then it got the full NASCAR Superbird treatment. Power comes from a 800 hp NASCAR-spec 358cid Dodge engine. The price is set at $250,000.

YearOne has teamed up with Gillette Evernham Racing, Musclecar TV and automaniac Bill Goldberg to create an updated legend — a NASCAR Superbird. “Goldberg said he wanted it to be as close to a real NASCAR as possible; for the street,” said YearOne project designer Phil Brewer. “It’s pretty much going to be an old-school NASCAR, in particular, how we’re going to handle the body.” To help with the direction of the build, cars from the Talladega Motor Speedway museum were photographed extensively. Period-correct NASCAR modifications include raising the transmission tunnel, moving the rear spring pockets further up into the floor, a stout X-brace to tie the sub-frames together, wheel tubs installed and a generous radius of the wheel openings. While the originals moved the torsion-bar cross member up into the floor, a more modern coil spring approach is going to be employed, which will simplify things and get the nose down. A full roll cage and early NASCAR-esque bare bones interior (with two seats) pretty much sum-up the office space. “Goldberg mentioned that he might want to do some top-speed stuff with the car, so it’s going to be built as though it is a competition car,” Brewer said. While the body is all retro, the power is all modern. Gillette Evernham Motorsports is contributing a NASCAR-spec 358cid Dodge engine, without the NASCAR-spec restrictions. Producing close to 800hp, the engine has been de-tuned enough to run on pump gas, but is otherwise pretty much off-the-shelf NASCAR. Backing it is a feather-weight Tex Racing 4-speed manual transmission feeding an 8 ¾-inch rear. At this point, the biggest problem with the design of the car was the wheel and tire package, as finding the right tires is proving difficult. “You can’t really run NASCAR slicks on the street,” Brewer said. “And modern tires just don’t look right.” While the plan for the Superbird is impressive, the reason it was built is even better.
