I read an article in a hot rod [?] mag 35 years ago about an L88 / C48 [?] vette, with M22 'Rock Crusher' tranny, that was believed to be 550 HP, 17x? MPH capable.
I know in retrospect that the article was about ZL1. Didn't mention rarity, that I remember. Not even a picture, but an artist Black & White sketch.
Hmmm...
Nothin' like boostin' your own thread
