A GM A-body of a different sort. Some may think it blasphemy to post a picture of Buick on the Super Chevy site, but you have to admit the 1970 Buick GS Stage 1 was the fastest American production car that year. Faster than a Vette or any of those rusting Mopars. When it comes right down to it, the guys on the Super Chevy staff are car guys period.
