The Potent 400 Cubic Inch W72 V8 and Four-Speed Manual: Under the shaker hood of this 1979 Trans Am resides the legendary 400 cubic inch W72 Pontiac V8 engine. Factory rated at 220 horsepower and 320 lb-ft of torque, this engine provided substantial performance for its time, delivering strong acceleration and a characteristic American V8 rumble. The W72 package was known for its improved cylinder heads, camshaft, and compression ratio compared to the standard 400, contributing to its enhanced output. This power is channeled to the rear wheels through a Borg Warner Super T-10 close-ratio four-speed manual transmission, offering drivers a direct and engaging connection to the car’s performance. Further enhancing traction is a Safe-T-Track limited-slip differential with 3.23:1 gearing, ensuring optimal power delivery to the road. In preparation for sale, the starter was replaced and the oil was changed, while the exhaust system was also replaced.

The Coveted WS6 Special Performance Package: This 1979 Trans Am is equipped with the highly desirable WS6 Special Performance Package, a factory option that significantly enhanced the car’s handling and braking capabilities. The WS6 package included power-assisted four-wheel disc brakes, providing improved stopping power compared to the standard front disc/rear drum setup. It also featured a quick-ratio steering box for more responsive handling and a larger sway bar, reducing body roll and improving cornering ability. These upgrades transformed the Trans Am into a more capable and enjoyable performance machine, making WS6-equipped models particularly sought after by enthusiasts today. In preparation for the sale, the brake master cylinder was replaced, ensuring optimal braking performance. The car rides on iconic 15-inch snowflake-style alloy wheels, fitted with BFGoodrich Radial T/A tires installed in March 2025.

Iconic Styling and Well-Preserved Interior: The exterior of this Trans Am is finished in the classic Platinum paint, complemented by the bold Firebird graphics on the shaker hood, a signature styling element of the era. The car features front and rear spoilers, contributing to its aerodynamic profile, and removable T-top roof panels, offering the open-air driving experience that was popular in the late 70s. Inside, the seating surfaces are trimmed in black cloth, providing a comfortable and period-correct feel. The interior features an engine-turned dash fascia, a full-length center console, and a Hurst shifter, further emphasizing the car’s sporty nature. An AM/FM radio provides classic entertainment, and a heater ensures comfort in cooler weather. The Formula steering wheel has been wrapped in leather and is mounted to a tilting column. Instrumentation includes a 100-mph speedometer and a 6k-rpm tachometer with an inset clock, along with gauges for oil pressure, coolant temperature, fuel level, and voltage. The five-digit odometer shows 38,000 miles. Recent interior work includes the repair of the dome light wiring and the replacement of the headliner in April 2025. Accompanied by its original window sticker, build sheet, and manufacturer’s literature, this 1979 Pontiac Firebird Trans Am WS6 represents a well-preserved example of a true American muscle car icon.
