FOR RELEASE: 2005-06-14 Legendary 1955 NASCAR Chevrolet Race Car Re-created

Junior Johnson Helps GM Celebrate 50th Anniversary of Small-Block V-8

DETROIT – Junior Johnson helped GM engineers introduce a re-creation of its 1955 Chevrolet at the GM Proving Ground in Milford, Mich. on June 8, 2005. The vehicle, built to commemorate the 50th anniversary of the GM small-block, was unveiled to select media and GM employees who were given rides in 1955 NASCAR Chevrolet at the GM Proving Ground with Johnson behind the wheel. Johnson also participated in internal employee events at the GM Proving Ground and the GM Warren Technical Center where the car was displayed and Johnson signed autographs.



Fifty years ago this September, Herb Thomas won the Southern 500 at Darlington driving a 1955 Chevrolet prepared by Smokey Yunick. It was Chevy’s first superspeedway victory and the beginning of a legend.



The GM small-block V-8 became, arguably, the most successful production and racing engine ever made. In fact, the small-block V-8 design is still raced today in NASCAR, ALMS, NHRA and many other series. Refined versions of the same proven design also powers many 2005 GM trucks, sport utilities, sedans and the Chevrolet Corvette.



This year a “new” 1955 Chevrolet NASCAR race car has taken shape at GM’s Performance Division Garage – a special project between GM Performance Division and the GM Heritage Center. Carrying Thomas’ famous number 92, it replicates Yunick’s original preparation and race specification as closely as possible.



“The re-creation of the 1955 Chevrolet NASCAR race car symbolizes the past, present and future success of the GM small-block V-8,” said Mark Reuss, executive director of GM’s Performance Division. “Fifty years later this engine design continues to deliver success on the race track while bringing real benefits to millions of GM owners in their personal and work vehicles.”



The racer is based on a 1955 Chevrolet “one-fifty” utility sedan which was inexpensive, lightweight and had no back seat. The replica will have a standard bench seat, “three on the tree” manual transmission, manual drum brakes, bias-ply ties with tubes and a small-block V-8 hopped up the way it’s believed Smokey would have done it. The engine of the original racer is currently in the Don Garlits Museum in Ocala, Fla., while the car itself has disappeared. Modern concessions to safety include a full roll cage, five-point safety harnesses, a fire suppression system and a dual circuit brake system. The current popularity of the classic 1955 Chevrolet made the parts and services necessary for the race car re-creation readily available.



Junior Johnson, winner of 50 NASCAR races and six Winston Cup championships as a team owner, is acting as a consultant on the car build and specification. NASCAR also provided research, reference photography and a copy of their 1955 rule book to help make the replica race car “pretty close” to the actual Chevrolets raced in 1955.



Johnson will drive the number 92 Chevy in its debut at the 2005 Goodwood Festival of Speed in England, June 24-26. Thereafter, the car will undertake a full program of appearances throughout 2005, celebrating the 50th Anniversary of the small-block V-8. These include the Woodward Dream Cruise, the Concours d’Elegance at Cranbrook and demonstration runs at individual NASCAR races.



The small-block crate engine is the world’s most popular choice for street rods and sportsman racers. More information on GM Performance Parts crate engines is available by visiting www.gmgoodwrench.com/PartsAccessories/GMPerformanceParts.html
