...to the best of my knowledge, there are none.

Cobra:The Real Thing probably has the most percentage of 427 info in it. It is out of print, but shows up on eBay and Used Booksellers from time to time.
The S/C is merely a footnote in most books. The real purist authors (in my opinion) believe that the 427 Cobra was the thing that put SA out of business and out of racing, and quite frankly, screwed up a good thing (the 289 Cobra). Thus, not many pages are devoted to it.
