    1976 Buick Century

    Offered for sale is a well-preserved 1976 Buick Century, a standout example of mid-70s American luxury and smooth cruising comfort, now enhanced with a performance upgrade under the hood for an extra dose of modern muscle. Finished in Independence Red Poly (37) with its long, clean body lines, semi-black vinyl top, chrome accents, and unmistakable Buick styling, this Century delivers the smooth ride and timeless presence these cars are known for.

    Under the hood, this Century packs a serious punch with a modern LSX 5.3L EFI V8 paired to a GM 4L60E automatic transmission, delivering dependable power with today's drivability. The 5.3L was fully rebuilt and upgraded with numerous performance internals, along with a complete EFI conversion and upgraded intake manifold for crisp throttle response and reliable performance. A BTR Stage 2 LS1/LS2 cam and Circle D 3000-stall converter bring the attitude, producing a strong, aggressive pull and a deep, unmistakable rumble. Supporting upgrades include a new driveshaft, fuel tank, and custom-fabricated exhaust system, while a polished aluminum radiator with twin electric fans keeps temperatures in check. The engine bay was refinished and detailed during the swap, giving it a clean appearance. It's the perfect blend of classic Buick comfort and modern muscle performance.

    It rides on 15-inch Retro black aluminum wheels wrapped in BF Goodrich Radial T/A tires for an aggressive, period-correct stance and confident grip. Power disc brakes up front paired with rear drums provide dependable stopping performance, making this Century as comfortable and capable to drive as it looks.

    Inside, the spacious red velour interior brings pure 70s luxury, with plush seating, a wide bench layout, and period-correct trim that keeps the vintage vibe alive. A B&M performance shifter adds a sporty touch and precise control, making every drive feel connected and fun. The dash features a modern digital speedometer paired with Auto Gauge tach, oil pressure, and water temp gauges, and an aftermarket stereo system adds today's sound quality while maintaining the vintage feel.

    Whether you want a comfortable weekend cruiser, a nostalgic daily driver, or a classic with modern muscle that is simply fun to drive, this Century delivers on every level. It fires right up, runs strong, and combines vintage Buick comfort with surprising performance that puts a smile on your face every time you hit the gas. Affordable, unique, and packed with personality, this is your chance to own a true piece of classic American iron with some serious punch under the hood. Also included with the sale is the original Buick Century build sheet.

    Don't miss out on this smooth-riding, muscle-backed Buick that is ready to hit the road. For more information, contact LRA Auto Museum and Sales at 215-781-3790 or email sales@lrasales.com.
