1970 Buick GS 455

The 1970 Buick GS represents the pinnacle of Buick performance during the muscle car era. Since General Motors lifted the ban on greater than 400cid engines in mid size models Buick was quick to build a 455 cid version in the Gran Sport line.

For the buyer looking for even more power there was the Stage 1 option. Though Buick claimed the Stage 1 system was only good for 10 hp, quarter mile times for Stage 1 Buicks were nearly a half second better than the standard GS 455 cid.

These improvements along with a 3.64:1 geared positraction made for nearly endless burnouts. With sticky tires a Stage 1 Buick was capable of low 13 second quarter mile times.

The GSX was first offered in 1970 and was essentially a trim package that included hood tachometer, Saturn Yellow or Apollo White paint, low profile spoiler, unique black striping and blacked out hood treatment, black bucket seats, floor shifter (Hurst for the four speeds) disc brakes, wide oval tires, quick ratio steering and upgraded suspension.

GS 455 - 8,710 hardtops and 1,416 convertibles. GSX production was limited to 678. Quarter mile performance for a Stage 1 was 13.4 seconds at 103mph.
