Refreshed Looks with Period-Correct Appeal
The car received a full repaint in Starlight Black during a 2024 refurbishment. It retains key styling elements like the shaker hood with Firebird graphics, front and rear spoilers, removable t-top panels, and color-matched mirror caps. Gold 17-inch Year One snowflake wheels give the car an authentic yet upgraded look.
Performance Upgrades with LS3 Muscle
At the heart of this Firebird lies a 6.2-liter LS3 V8 engine, installed in 2024. It features PRC cylinder heads, a Texas Speed camshaft, an Edelbrock throttle body, Holley fuel rails, and long-tube headers. Supporting hardware includes a Cold Case radiator, MSD ignition wires, and a Holley EFI fuel tank.
Power is sent to the rear wheels through a Tremec T-56 six-speed manual transmission. The car features a limited-slip differential with 3.73:1 gearing. A McLeod hydraulic clutch kit, LS7-style clutch, Holley cross-member, and dual stainless exhaust with Pypes mufflers complete the setup.
Enhanced Handling and WS6 Equipment
Thanks to the WS6 Special Performance Package, the Trans Am benefits from upgraded suspension and braking. It includes power-assisted four-wheel disc brakes, a quicker steering box, larger sway bar, and power steering. Adjustable front coilovers and drilled, slotted rotors further improve control and road feel.
Custom Interior with Classic Vibes
Inside, black vinyl upholstery covers the retrimmed seats and door panels. The cabin includes a full-length center console, engine-turned dash, Hurst shifter, aftermarket air conditioning, and a digital stereo. The Formula steering wheel fronts classic gauges, including a 160-mph speedometer and tachometer.
Restoration and Provenance
The Trans Am was refurbished and modified in 2024 before being acquired in 2025. A copy of the build sheet confirms its original delivery to Bridges Pontiac in Hayward, California, and lists factory colors and options. It is now offered with PHS documentation and a clean Illinois title.
Summary
This 1978 Pontiac Firebird Trans Am blends muscle car nostalgia with modern mechanicals. Its powerful LS3 engine, upgraded suspension, and six-speed transmission make it a thrilling and stylish driver’s car for collectors and enthusiasts alike.
