1973 Pontiac Firebird Formula 350 in Sunlight Yellow: A Slice of American Muscle

The 1973 Pontiac Firebird Formula 350 represents a golden era of American muscle cars, blending iconic styling with robust performance. Sporting its distinctive split grille and sleek silhouette, the Firebird Formula was Pontiac's sophisticated alternative to pure muscle machines. This particular example, finished in Sunlight Yellow (code 51), pays homage to the Firebird’s enduring legacy while showcasing tasteful upgrades and well-preserved originality.

Performance and Power

At the heart of this Formula 350 is its numbers-matching Pontiac 350 V8 engine, paired with a Turbo 350 three-speed automatic transmission. Factory-equipped with the Y99 handling package, this Firebird features front and rear sway bars for an improved ride and agile cornering. The engine breathes through a Holley carburetor and Edelbrock aluminum intake, while its exhaust system, enhanced with Flowmaster mufflers and an X-pipe, delivers a deep, aggressive tone.

Interior and Features

The Saddle interior (code 243) contrasts beautifully with the Sunlight Yellow exterior, offering a retro vibe that captures the early 70s spirit. Features include:

• Bucket seats and center console: Classic muscle car staples that provide comfort and a sporty feel.

• Vintage Air system: Keeps the cabin cool with modern efficiency, perfect for spirited drives on warm days.

• Classic Auto Sound stereo: A subtle upgrade that maintains the period-correct look while allowing modern audio functionality.

The dash and gauge cluster present well for their age, while original elements like door panels and trim reflect the car’s authenticity. The upholstery shows minor wear, and the rear seat remains in excellent condition.

Exterior and Undercarriage

Repainted in its original Sunlight Yellow, this Firebird exudes a vibrant, timeless charm. The body is solid with minimal imperfections, and its 15-inch Pontiac Rally wheels wrapped in Mastercraft 245/60 tires complement its aggressive stance. The undercarriage is as impressive as the exterior, featuring original floor pans with signs of factory red oxide and solid inner rockers. Updates to the suspension include newer front and rear shocks and rear leaf springs, ensuring a smooth ride.

Additional Notes and History

This Firebird is accompanied by Pontiac Historical Services (PHS) documentation, verifying its authenticity and factory options. While the odometer reads 2,021 miles, the actual mileage is unverified, consistent with its age and restoration history. Its California title adds to its appeal, reflecting its long-standing preservation in a dry climate.

The Formula Difference

The Firebird Formula 350 was Pontiac’s answer to those seeking a balanced mix of performance, comfort, and style. The dual-scoop hood, Rally wheels, and Y99 handling package set it apart from standard Firebirds, while its V8 power ensured it could compete with the era’s muscle cars.
