I'm not saying that this book is the mopar holy gail, but it is one of the most comprehensive of the very few B-body restoration books available, and has had an influence on most factory restorations completed since its publishing.

The book also says on page 23,

"A few 383/335hp V-8's were painted turquoise when equipped with air conditioning."

Again on page 29,

"Note that some 1969 and 1970 383s in
air-conditioned Super Bees and Road Runners were painted Turquoise."

On page 40 (picture caption)

"Cars sold in California in 1969 used a dual snorkel air cleaner with the high performance 383ci and 440ci powerplants."
