The '69 Imperial engine color should indeed be turquoise. Imperial engines were turquoise through '71, then switched to blue for '72. The blue on the '74 Imperial shown is correct.My questions are should the engine color on a 69 Imperial be turquoise and is the color on this 74 Imperial car correct assuming that it is not turquoise but blue? Should the air cleaner on a 74 Imperial say 440 or Imperial?
