1970 GSX: As one of the Top 10 Muscle Cars of All Time, the Buick 1970 GSX has certainly carved its place in American motor history. In the years preceding this particular model, General Motors had limited itself to a 400 cid engine. However, by the time 1970 rolled around, the desire for a little more power under the hood was finally too much to bear, and GM lifted the limit. In the GSX, a GS 455 V-8 replaced the 400 cid V-8.
