The iconic styling of the late seventies Trans Am holds a special place in automotive history, often recalling the famous Starlight Black T-top muscle car. However, this particular 1978 Pontiac Firebird Trans Am sheds its movie-star legacy for serious modern performance. Initially restored in 2008 by a specialty shop that has since evolved, this is no stock relic. It is a highly modified pro-touring machine, currently powered by a massive 572-cubic-inch V8, transforming the classic Firebird into a genuinely formidable road weapon.
The Starlight Black Exterior
The Trans Am’s dramatic bodywork is finished in the factory-correct Starlight Black. This glossy canvas features a striking gold-airbrushed eagle graphic on the shaker-style hood, perfectly complementing the era’s aesthetic. Exterior details include a front lip spoiler and vented fenders which add to the muscular profile. The presence of removable glass T-top roof panels maintains the quintessential 1970s performance look.
Subtle Changes to an Aggressive Stance
The car’s appearance is not simply a restoration but a purposeful evolution. Remote door poppers offer a subtle modern convenience. The rear of the car features a lip spoiler and quad exhaust outlets. While retaining its classic appeal, the vehicle’s overall presentation hints at the powerful changes lying beneath the skin.
Chassis and Suspension Upgrades
Underneath the classic sheet metal lies a thoroughly modern and reinforced chassis built for high-level handling. A revised front subframe and rear wheel tubs that have been widened accommodate the performance hardware. This work was critical to handle the immense power output of the new engine installation.
Tuning the Ride for the Track
The lowered suspension boasts a significant list of high-end components. These parts include aftermarket sway bars and tubular control arms at the front end. The rear axle uses robust traction bars for better grip during aggressive acceleration. All four corners feature adjustable QA1 coilovers, allowing the current owner to fine-tune the ride height and damping characteristics. This setup gives the Trans Am a contemporary performance feel.
Stopping Power and Rolling Stock
Translating power into controlled motion requires substantial braking and a strong wheel-tire package. This build addresses those needs with oversized components. Gold-finished 19-inch Forgeline web-spoke alloy wheels anchor the car visually. They were mounted with high-performance Continental ExtremeContact tires in preparation for the sale.
Baer Brakes for Controlled Deceleration
Braking is handled by an advanced system from Baer, featuring upgraded big brake kits on both axles. These powerful gold six-piston calipers grab slotted and cross-drilled rotors. This combination ensures phenomenal stopping power, providing necessary confidence when handling the car’s prodigious speed capabilities.
Inside the Custom Cabin
The Trans Am’s interior has been fully retrimmed in black leather that covers the front bucket seats and custom individual rear seats. This luxurious material extends seamlessly to the dashboard, door panels, and center console. A functional roll bar hints at the car’s readiness for high-speed driving.
Modern Tech and Classic Instruments
Appointments include a Hurst shifter for precise gear changes. Air conditioning provides necessary comfort for cruising. Instrumentation remains gold engine-turned, featuring a 100-mph speedometer and a 10k-rpm tachometer. For entertainment, a Bluetooth-capable Alpine stereo system links to a custom Focal sound system. A Viper alarm system adds security to the highly valuable machine.
The Heart of the Beast: Merlin 572 V8
The true story of this 1978 Pontiac Firebird Trans Am rests with its powertrain. The all-aluminum 572ci Merlin V8 features numerous modern upgrades for increased reliability and sheer output. A high-torque mini starter and a 140-amp alternator support the electrical systems. The engine is managed by a Holley Terminator X electronic fuel injection system. Fuel delivery is handled by 1,000cc Fuel Injector Clinic injectors and a Holley Dual-Sync distributor.
Engine and Driveline Performance
The colossal V8 engine channels its power through long-tube headers and a custom dual exhaust system. Magnaflow mufflers ensure an aggressive sound profile. Power is routed through a hydraulically actuated McLeod RXT twin-disc clutch for reliable engagement. A recently resealed Tremec Magnum six-speed manual transmission sends power to a modified Ford nine-inch rear axle. This rear end features a limited-slip differential and 3.70:1 gearing, providing optimal acceleration and traction. An aluminum radiator and dual electric cooling fans keep the massive V8 running cool under pressure.
Summary of a Pro-Touring Icon
This 1978 Firebird Trans Am is a stunning example of pro-touring conversion, successfully marrying classic style with potent, modern performance engineering. The attention to detail, from the widened wheel tubs to the custom V8 engine components, reflects a commitment to building a truly exceptional machine. It stands as a testament to the enduring appeal of the Trans Am shape, now backed by the raw power and handling capabilities of a contemporary supercar.
