This 1977 Pontiac Firebird Trans Am is a meticulously executed restomod that reimagines one of America’s most recognizable performance icons through the lens of modern LS-based power, upgraded chassis dynamics, and refined drivability. Combining the unmistakable presence of a late-1970s Trans Am with a professionally engineered 417ci stroker LS3 V8 and six-speed manual transmission, this build delivers a compelling blend of vintage character and contemporary performance capability.
Refinished in black over black and gold upholstery as part of a comprehensive refurbishment completed by GKR Motorcars of New Bloomfield, Missouri, the car retains the unmistakable visual identity of Pontiac’s Y82 Special Appearance Package. Originally finished in Starlight Black (19), the Trans Am underwent a full repaint during the refurbishment completed in 2023, along with additional bodywork to the lower rear quarters and rear structure, as well as repairs addressing previously noted passenger-side damage. Signature styling elements remain intact, including gold accent graphics, shaker hood, quad rectangular headlights, fender vents, rear decklid spoiler, and Trans Am badging, all of which preserve the car’s iconic and instantly recognizable silhouette.
Underneath, the chassis has been significantly upgraded to match the performance potential of its modernized drivetrain. A Currie 9-inch rear axle with a 3.70:1 limited-slip differential provides a durable foundation for high-output use, while UMI Performance control arms, Viking adjustable front coilovers, Viking rear shocks, Detroit Speed rear leaf springs, and upgraded sway bars work together to deliver improved handling precision, stability, and road control. The result is a Trans Am that maintains its classic muscle car feel while offering a substantially more composed and responsive driving experience.
The car rides on 17-inch snowflake-style alloy wheels with gold accents, mounted with Michelin Pilot Sport 4S tires that provide modern grip and performance. Wilwood four-wheel disc brakes with six-piston front and four-piston rear calipers deliver confident and consistent stopping power, ensuring the chassis upgrades are fully supported by braking capability.
Inside, the cabin has been retrimmed in black upholstery accented by gold-patterned Recaro front bucket seats, blending motorsport-inspired support with period-correct styling cues. The interior is equipped with Vintage Air climate control, power windows, a wood shift knob, bright sill plates, and a vintage-look stereo system that integrates modern usability without compromising the classic Trans Am aesthetic.
The driver is met with a microsuede-wrapped steering wheel and a Dakota Digital instrument cluster set within an engine-turned dash panel. The digital display includes a 160-mph speedometer, 8,000-rpm tachometer, and auxiliary readouts for oil pressure and coolant temperature, providing clear monitoring of the upgraded powertrain. The digital odometer indicates approximately 1,400 miles, with total chassis mileage unknown.
Power is provided by a 417ci stroked LS3 V8 featuring Holley Terminator electronic fuel injection and a 102mm electronic throttle body, delivering modern throttle response, reliability, and substantial performance output. Supporting components include Racetronix fuel rails, an aluminum radiator, a CVF Racing serpentine drive system, long-tube headers, and Trans Am-branded billet valve covers, all contributing to a clean and highly functional engine bay presentation.
Power is routed through a Tremec T56 six-speed manual transmission paired with a McLeod clutch, offering direct, engaging gear changes and strong driver involvement. A Currie 9-inch rear axle with a 3.70:1 limited-slip differential completes the drivetrain, ensuring effective power delivery to the pavement.
This 1977 Pontiac Firebird Trans Am represents a well-executed fusion of classic American styling and modern performance engineering. With its stroked LS3 powerplant, extensively upgraded chassis, Wilwood braking system, and carefully preserved Y82-inspired aesthetic, it delivers the unmistakable presence of a late-1970s Trans Am combined with the performance and usability of a contemporary restomod built to be driven and enjoyed.
