1970 Buick GS 455 Stage 1 Sport Coupe

In 1970 General Motors removed its self-imposed 400 cu. in. limit on V-8 engines, leading each GM division to develop its own engine that pushed the envelope in size and “reported” horsepower. Typically seen as General Motors’ mid-level luxury division below Cadillac, Buick joined the race with its new big-block 455 cu. in. V-8. The engine would find its way into the 1970 Buick GS 455, even lending its name to the model. The GS or Gran Sport 455 was GM’s luxury muscle car. It came with numerous power options, an upgraded interior, and most important, exhilarating performance.
