As to the question about pictures in the correct color, I do not have any but you might be interested in some in Mustang Monthly. I did a search on the internet for Ford engine color and came across their article on the subject. In it they talk about the darker Ford Blue that was adopted across all engine lines in 1966. I cannot vouch for them as a reliable source or not but their article has the following information that I have cut and pasted here:
"We've learned through observation andconversation with restorers that Duplicolor's Dark Ford Blue (1606) is an accepted color for '66 and later Ford engine restorations. An alternative, when Duplicolor isn't available, is Krylon's Dark Ford Blue, which is also the correct shade of dark blue. Plastikote is another paint brand, Royal Blue (1134) an acceptable color for '66 and later."
Again, some pictures are in the article.
