Shame on Rupe for posting such blasphemy! That’s a beautiful Buick he mentions, and it is indeed rather quick; however, its weight alone will prevent it from standing up to any of the hemi-Mopars mentioned- particularly the ‘70 Hemi-Cuda!
The fastest hemi cars are the 1968 hemi cuda’s, just edging out the 1968 hemi darts. The fastest street legal Hemi’s are the 1965 super stocks, the only hemi with aluminum heads, again with the very slight edge maybe going to the Plymouth. Then next are the hemi equipped 1964 super stocks.
WHERE IS THE 71′ hemi ‘cuda cv?
Buick GSX Stage 1 was the fastest muscle car of 1970.
Rupe, what is your historical source for your claim? Here’s mine. According to the automotive magazines cited in this article, the Buick GSX was the 8th fastest muscle car in 1970.
