The Real Story Behind The 1955 Chevy Gasser From ‘Two-Lane Blacktop’

Richard Ruth’s Competition Engineering built three 1955 Chevrolet 150s for Two-Lane Blacktop, not one car with a single definitive specification. Their engines and roles differed, and one primary car later became Bob Falfa’s Chevy in American Graffiti.

The familiar “1955 Chevy” from Two-Lane Blacktop was not one universally specified car: Richard Ruth’s Competition Engineering built three 1955 Chevrolet 150 two-door sedans for the 1971 film. Two were primary picture cars with different engines and roles; a third was an all-steel stunt car. One of the primary cars later became Bob Falfa’s black Chevy in American Graffiti, while the surviving interior camera car was restored and sold in 2015.

Three Chevys, not one

Richard Ruth built the three cars based on his own big-block 1955 Chevy. Accounts that call the film car a 427 or a 454 can both be right, depending on which vehicle and configuration they describe. The exterior picture car had a 427; the interior camera car had a 454; and the separate steel-bodied stunt car also had a 454.

Car Film role and configuration Known equipment
Exterior picture car Primary car used for exterior shots in Two-Lane Blacktop 427 crate engine, M-22 Muncie transmission, 4.88 Oldsmobile rear, fiberglass panels, and a straight axle as originally built
Interior camera car Primary car used for interior camera work 454 crate engine and similar core drag-car equipment; the surviving car is described with a 454 and M22 four-speed
Stunt car Separate all-steel car 454 engine, TH400 automatic, and an Oldsmobile rear with gearing not specified in the research

These are reported configurations, not a claim that every component stayed unchanged. Equipment differed between cars and could change over time, including in later film or restored configurations.

Why the Chevy matters in the film

The Library of Congress describes Two-Lane Blacktop as a cross-country race between the Driver’s Chevy and a Pontiac GTO that gradually becomes a roadside odyssey. The car is central to that journey, but the film is not simply a conventional racing story. Director Monte Hellman described the film’s outlook this way: “I am romantic in the way the Camus is romantic,” said Hellman. “I feel a nostalgia for what can never be.”

Ruth’s cars were built for drag-racing use, with equipment such as a custom straight axle, fiberglass body panels, sliding Plexiglas windows, a tunnel-ram intake, and dual carburetors. Those details help explain the recognizable gasser look, but they should not be treated as one fixed specification shared by all three cars.

Was the Chevy also Bob Falfa’s car in American Graffiti?

One of the primary Two-Lane Blacktop cars was modified for American Graffiti. It was painted black and received changes to its interior, windows, trunk, wheels, and hood scoop, becoming Bob Falfa’s Chevy. Richard Ruth later examined detailed photographs and authenticated it as one of his original builds for Two-Lane Blacktop.

That later identity belongs to one car, not all three. It is also why descriptions of the Chevy can differ: accounts may be discussing a particular picture car, the stunt car, or a car after its later movie modifications.

What happened to the surviving interior car?

After filming, the interior car went to a studio mechanic and later passed through other owners. It was located in Canada in 2000. Walt Bailey brought it back to the United States and worked with Ruth on a preservation and restoration project.

Sports Car Market reports that the car sold at Barrett-Jackson Scottsdale on January 17, 2015, for $159,500 including buyer’s premium. That is a historical auction result, not a current valuation or evidence of the car’s present ownership or display location.
