I'm not a GM guy but I heard that there were 17 units built (from old sources) of the1970 Chevelle SS 454 LS6 convertibles total built...and I don't know when the first production of them were first built, but I am curious if they were legal according to NHRA rules, (50 units)...ooooh, it looks like someones here is stirring the pot a little bit, lol.
