Buick GS 455 Stage 1: The Fastest Muscle Car In 1970

When we think of the American muscle cars of the golden era, legends such as the Ford Mustang, Pontiac GTODodge Charger and even the Chevrolet Chevelle are sure to come to mind. Buick sports cars were kind of on the sidelines. The company preferred not to intervene in a fierce battle, giving the muscle car market at the mercy of colleagues from the GM concern. But in 1970, Buick finally decided it was enough to sit in the shadows and released the incredible Stage 1 Buick GS. However, it was too late.

By the early 1960s, Buick had developed an image as a luxury car manufacturer for a successful family man. Not as luxurious as the Cadillac, of course, but the Buicks cost quite a lot. In 1964, the release of the first “muscle car” – the Pontiac GTO and the emergence of a new market, Buick marketers can be said to be ignored.


Only in the middle of 1965, the company was able to equip its mid-size Buick Skylark with a 401 cc engine. inches (6.6 l) and 325 hp. The modification was called Gran Sport and was offered for $ 457 in a version with a two-speed automatic transmission. By that time, competitors in the face of the same GTO or Chevelle SS were already offering engines for 350-360 forces, and they were much cheaper. However, the Buick Skylark Gran Sport had its advantages in the form of improved trim and equipment. Nevertheless, the company managed to sell 16,000 cars in the first year. The result against the background of 80 thousand at Chevelle is not impressive. Nevertheless, they were not going to roll back from the promising market in Buick.


In 1967, the Gran Sport modification was separated into a separate model – the Buick GS. By that time, a completely new 400 cc V8 engine was prescribed under the hood of the car. inches Unlike its predecessor, the motor had a short stroke design, a new cylinder head with larger valves and a hemispherical combustion chamber. As a result, engine power increased to 340 hp. But this is according to the passport. At that time, insurers had already begun to raise tariffs for muscle cars, due to their high accident rate. Therefore, automakers simply began to underestimate the power of their engines. In fact, the big-block Buick V8 developed a power of about 360 – 370 hp. According to Car Life’s test results, the Buick GS-400 accelerated from 0 to 60 mph in 6.6 seconds and covered the quarter mile in 14.7 seconds. In those days it was very, very fast.


In the late 60s, the power race reached its zenith. Most American automakers have already released their “muscle cars” with engines in excess of 400 cc. inches Buick also did not stand aside and in 1969, unexpectedly for competitors, introduced the Buick GS with a monstrous 7.5-liter V8 and 350 hp. A Stage 1 modification was also offered with a four-barrel Rochester Quadrajet carburetor, which produced 10 hp. more. But don’t let these numbers fool you. In reality, the motor produced more than 420 hp. This is confirmed by the measurements of Motor Trend magazine conducted in September 1969. On them, the Buick GS 455 Stage 1 covered the quarter mile in 13.38 seconds. For example, a Plymouth Cuda equipped with a 425 hp Hemi engine, according to the measurements of the same publication, passed the “quarter” in 13.78 seconds! The agility of the Buick GS 455 was so impressive that Motor Trend called it the fastest muscle car ever tested. Here is such a grandfather Buick.


However, the engineers did not intend to stop there and prepared an even more impressive racing package called Stage 2. It included a modified engine with a racing camshaft, forged pistons, a new intake and exhaust system, and a more efficient carburetor. Moreover, unlike many other “muscle cars” of that time, the GS in this modification on the hood had functional air intakes of kinetic (high-speed) boost.


The estimated power of the Buick GS 455 Stage 2 was 540 hp. Buick is known to have built only three cars. One of them was prepared for drag racing where factory driver Bill Trevor was able to cover the quarter mile in an incredible 10.7 seconds! Fortunately, the Stage 2 package was not released to the public. Its limited version was added as a dealer option, while breaking the fabulous price.
