Bob, thanks for clarifying on the engine photo and I certainly have no reason to doubt that the picture itself is that of a 1966 setup. In fact, it makes total sense to me that they would have simply reused an existing photo since the changes were so minor for '67. However, even though it isn't a full article, the advertisement's print specifically reads, "An original equipment option on the fabulous new 1967 GT 350," and I believe that's what Fastback66 was searching for.
