|The GSX is now on the options page for 1971|
|The 1971 GSX was announced in this bulletin from Buick Car Distribution|
|As per this bulletin, the front and rear spoilers and hood tach were separate options.|
|Here are the six colors for 1971|
For 1971, power on all the GS models were reduced. The standard 350 now developed 260 hp, the optional 455 produced 315 hp, and even the 455 Stage 1 now developed 345 hp. Compression on all engines was lowered across the board to 8.5 to 1, down from 10.5 to 1 on the standard 455 and 10.5 to 1 on the Stage 1. Clearly the handwriting was on the wall and the performance car as we knew it was on the way out.
A total of 124 GS coupes had the GSX option in 1971, only about a quarter of what were sold in 1970, but it is worth noting that they are still very potent and desired classics, and the 455 Stage 1 was still the most popular engine in 1971, even with the reduced compression.
Here are all of the approved colors for the 1971 GSX:
|Arctic White- Code C|
|Cortez Gold- Code Q|
|Lime Mist- Code H|
|Platinum Mist- Code P|
|Stratomist Blue- Code B|
|Bittersweet Mist- Code T|
