----Grant,,,I don't recognize the contraption on the right rear of the intake with all the green stripe vacume (sp) lines going to it. Is that California only, and what does it do?......Bill S

Bill... that's correct, the '67 CA cars with manual trans and A.I.R. were the first to use this valve together with a dual port vacuum advance that both advances and retards timing. It was also used on '68s and some '69 applications. Not sure exactly how it functions, but I hope it all works!

Bill... this is from my service manual and explains how the valve functions.
