    All Q-jet carbs use the same spreadbore bolt pattern. They will bolt to the intake, and automatic and A/C makes no difference. There can be some interference issues with some throttle linkages and certain intakes, but that is rare. Buick Q-jets have a front mounted fuel inlet, Chevy Q-jets have side mounted inlets. Not a big deal unless you want it to look correct and you don't want to change your fuel line.

    71-74, but ONLY the 455 carbs. All 350 carbs were 750

    I may have sourced this rebuilt carb from an ebay merchant. Seen as its a 74 455 i should be good to go aye?

    Yes, it's a 455 carb, so it is an 800 CFM unit.
