There is a chart in the Mopar Performance catalogs, but it relates mostly 
  to the later 1960s cars when Turquoise was the basic engine color for the B/RB 
  motors.  As I recall, the wideblock 318s were med-dark red, the Chrysler 
  Blue came into the mix in the later times after Turquoise, about the same time 
  that Hemi Orange was added to some of the HP motors. 
   
  Back in the "Golden Lion" engine nomenclature, seems like the engine 
  color might have been gold.
   
  For the air cleaners, I suspect that black would be operative.  The 
  best match I've found for that paint is, sorry about the source, GM Glossy 
  Black Engine paint, part number 12346297 or replacing numbers thereof.  
  It was a dead-on match for the air cleaner paint on my '67 Chrysler plus 
  anything else under there that's black. The "glossy" part in the name is not 
  entirely accurate as it's a satiny gloss black instead of a highly shiney 
  black paint.  Air cleaner, a/c hard lines, brackets--it works in all of 
  those places.  For the a/c lines, I gently sprayed in into a glass bottle 
  and then used a camel hair hobby brush to apply it to the a/c lines (after 
  wiping them down with brake cleaner and B-12).  It took a few 
  applications, but it looked good PLUS no disassembly.
   
  
   
  Enjoy!
