The 1973 Pontiac Trans Am Super Duty 455 is often hailed as one of the last true muscle cars of the classic era. At a time when the muscle car market was dwindling due to increasing emissions regulations and the oil crisis, Pontiac boldly introduced the Super Duty 455, a car that embodied the raw power and performance that enthusiasts had come to love. The 1973 Super Duty 455 remains a highly coveted classic, celebrated for its formidable engine, aggressive styling, and enduring legacy.
A Bold Design
The 1973 Trans Am featured a bold and aggressive design that made it stand out from the competition. The front end was characterized by a "shovel-nose" grille and distinctive quad headlights, giving the car a menacing look. The iconic "screaming chicken" hood decal, which covered the entire hood, became a hallmark of the Trans Am's design and symbolized its performance prowess.
The Trans Am's sleek lines, flared fenders, and aerodynamic profile contributed to its muscular and sporty appearance. The car was available in several vibrant colors, including Buccaneer Red and Brewster Green, which further emphasized its bold and dynamic character.
The Heart of the Beast: The Super Duty 455 Engine
At the core of the 1973 Pontiac Trans Am Super Duty 455 was its namesake engine, the 455 cubic inch (7.5 L) V8, known as the Super Duty 455.

The Super Duty 455 produced an impressive 310 horsepower and 390 lb-ft of torque, making it one of the most powerful engines of its time.
The engine's power was transmitted through a choice of a 4-speed manual transmission or a 3-speed Turbo Hydra-Matic automatic transmission.
