Barrett-Jackson will auction this custom 1961 Nash Metropolitan in Scottsdale, Arizona on January 11-19. The little dragster was built by Rodger Purdy Jr. from Pro Street Chassis in New Jersey. It rides on a custom tubular chassis with a Mustang II front suspension and four-link rear suspension. A 540 ci Chevy big-block V8 with Pro Comp aluminum heads capable of 620 horsepower sticks out of the hood. Power is sent to the rear wheels through a Transmission Specialties Turbo 400 3-speed automatic transmission and Ford 9-inch rear end with a LSD and 4.10 gears.
