I just received from GM an info package on the 71 chevelles, it does list an LS6 being available in 71. However as said before, I have been told that engine factory records show none were built for production. The 71 sales brochure does not mention the 450 hp LS6, it only offers up the 365 hp LS5. This is still somewhat of a mystery, although I would not buy a 71 from a guy saying its a 71 LS6 (99.9% chance its not) ...just my .02.
