Jeff.....BTW......The installation sheet for my Edelbrock Q-Jets says to hand tighten down the mounting bolts with a box wrench and to be careful because over tightening will break the base of the carb!! Also on this sheet it calls the vacuum port you circled on the side of the carb below the choke assembley a " diverter port " ?? don't know what that is but my other info shows it going to the air cleaner ........none the less mine is blocked off and the carb works great.
