Personally I too prefer 67 Camaros over 68's also really love stinger hoods on almost anything other than non '67 mid year 'Vettes..
But when it comes to Yenkos, the 68's w/ their 140 Speedo and MM tag make me lean their way to start with but those '68 hoods put me over the top so I'm weak in the knees for a '68 more than a '67 and would prefer either of them over a '69 anyday!.
