Now that I come to think about it, I am not so sure there was a designation for a SB or BB Super Sport other then L78.
I have seen Z27 on 1971 Camaros but I don't remember if the 1970 SS had a trim tag designation. I didn't think it did. Anyone?
Also he states 396/325hp when in 1970 it was 396/350hp. The LS3 in 1971 was rated at 300hp.
Things don't add up.
