As Buick’s ultimate performance car, the GSX combined luxury with raw power, making it one of the most impressive and sought-after muscle cars of its era. The 1970 model year, in particular, marked the pinnacle of the GSX’s development, cementing its status as a true icon in automotive history.
Bold and Aggressive Design
The 1970 Buick GSX was designed to turn heads and make a statement. It was available in two striking color options: Apollo White and Saturn Yellow, both featuring bold black racing stripes that ran the length of the car. The GSX package included a front chin spoiler, rear deck spoiler, and unique badging, giving the car a distinctive and aggressive look.
The GSX’s design was further enhanced by its wide stance, flared fenders, and hood-mounted tachometer, which added to its muscular and performance-oriented appearance. The combination of these elements made the GSX instantly recognizable and a standout on the road.
The Heart of the Beast: The 455 V8 Engine
Under the hood, the 1970 Buick GSX was powered by a massive 455 cubic inch (7.5 L) V8 engine, available in two configurations. The standard engine was the 455 Stage 1, which produced a staggering 360 horsepower and an incredible 510 lb-ft of torque, making it one of the most powerful engines of its time. This engine featured high-performance components, including a high-lift camshaft, large valves, and a high-flow exhaust system.
For those seeking even more power, Buick offered the Stage 2 package, which included additional performance upgrades and increased the engine’s output to an estimated 400 horsepower. The Stage 2 package was incredibly rare and is highly prized by collectors today.
Performance and Handling
The 1970 GSX was more than just a straight-line performer; it was designed to handle and stop as well. The car featured a heavy-duty suspension system with performance-tuned shocks and springs, providing a balance of comfort and agility. Power front disc brakes were standard, ensuring that the GSX could stop as effectively as it could accelerate.
The GSX’s performance was further enhanced by its standard 4-speed manual transmission, which allowed drivers to fully engage with the car’s power. An optional Turbo Hydra-Matic 400 3-speed automatic was also available for those who preferred a more relaxed driving experience.
Interior Comfort and Luxury
Inside, the 1970 Buick GSX offered a blend of performance and luxury. The cabin featured high-back bucket seats, a center console with a floor-mounted shifter, and a sporty dashboard with round gauges. The GSX’s interior was designed with the driver in mind, providing a comfortable and engaging environment.
Despite its performance focus, the GSX didn’t sacrifice comfort. The car offered a range of options, including air conditioning, power windows, and a premium audio system, making it a well-rounded package for both daily driving and high-performance fun.
Rarity and Collectibility
The 1970 Buick GSX is one of the rarest and most collectible muscle cars of its era. Buick produced only 678 units of the GSX in 1970, making it a highly sought-after model among collectors. The combination of its striking design, powerful engine, and limited production numbers has driven its value to impressive heights.
Well-preserved examples of the 1970 GSX command premium prices at auctions, with Stage 1 and especially Stage 2 models fetching top dollar. The car’s rarity, historical significance, and performance credentials make it a prized possession for muscle car enthusiasts.
