i think i'd work with the stock avs before i blew money on the edelbrock. the only real issue with the stock carbs is the lean idle/low speed circuit. the automatic transmission carbs have a leaner idle jet than the manuals. just set the carb up for the manual idle jet and make sure the mixture screws at the base of the carb are useable, .i prefer the edelbrock accelerator pumps to the old stock leathers, and i use edelbrock squirters but that's not a must. whole lot cheaper to do this than $400.
