Does anyone have a link for a vacuum hose diagram for a '74 318, Edelbrock intake and 650 cfm, manual transmission. Thanks for any help. I don't know what year the underhood stickers with vacuum diagrams started. It may not have been until '74 or '75. The owners manual diagrams are sometimes helpful. Also if you haven't already. Check through Master Technician Service Conference - Chrysler's Training for Mechanics and The 1970 Hamtramck Registry Library Page (1970 - 1974)
