Never saw pics of either of these two engines before, not even old H-R magazines.

"The triple-row timing chain above looks rather stout (and not nearly as long as the Ford SOHC 427’s seven-foot timing chain)"....Exaggeration.Its only six feet.

And I'll be that chain is at least five feet long.  The triple row was probably a good idea, though...

   The DOHC was on the cover of Hot Rod. Red background with Zora in the photo. ( '67 maybe)
