Gorries Black Panther Camaro road test from the May '67 issue of Canada's Track & Traffic magazine, courtesy of Mike Scott (group/7).
The Black Panther package was available on any V-8 model, although I'm not sure about a convertible. There were even two '67 Z-28s
converted into Black Panthers. The car in the article is 427-powered although, for some odd reason, the engine shown is a small block.
