THIS 1973 PONTIAC FIREBIRD IS LOCATED IN: BRIGHTON, CO 80603

The Pontiac Firebird is an American automobile that was built and produced by Pontiac from the 1967 to 2002 model years. Designed as a pony car to compete with the Ford Mustang, it was introduced on February 23, 1967, five months after GM's Chevrolet division's platform-sharing Camaro. This also coincided with the release of the 1967 Mercury Cougar, Ford's upscale, platform-sharing version of the Mustang.

The name "Firebird" was also previously used by GM for the General Motors Firebird in the 1950s and early 1960s concept cars.

Second generation (1970–1981)

The second-generation debut for the 1970 model year was delayed until February 26, 1970, because of tooling and engineering problems; thus, its popular designation as a 1970½ model, while leftover 1969s were listed in early Pontiac literature without a model-year identification. This generation of Firebirds were available in coupe form only; after the 1969 model year, convertibles were not available until 1989.

1973

In 1973, the Trans Am added two new colors, Buccaneer Red and Brewster Green. Other exterior upgrades included the updated more modern nose bird. The new hood bird was option “RPO WW7 Hood Decal”, a $55 option exclusive to Trans Am. The “Trans Am” decals were larger than previous versions and shared the same accent color schemes as the hood bird.

Inside the 1973, Firebird the standard interior equipment was almost the same as prior years. The new “Horse Collar” optional custom interior featured new seat coverings and door panels. The 1973 Firebird also had to meet the new safety and emissions requirements for 1973. There were extra steel reinforcements in the bumper and core support to the fender.

The 1973 Trans Am engine displaced 455 cubic inches in the base L75 and the Super Duty LS2 option. The base 455 produced 40 fewer horsepower than the round port Super Duty 455. Horsepower for the base L75 455 was rated at 250@4000 rpm and 370 lb/ft @2800 rpm. Pontiac removed the H.O. designation from the base engine, and simply decaled the now non-functioning shaker with “455”.
