4 barrel Quadrajet from 1973 Buick Auto. I bought this as I needed the choke parts for my Trans Am. This carb is described in my Quadrajet tuning book as second only to the 455sd carbs in terms of performance. I have never ran this and it has been sitting for some time. I took the top off and it appears complete inside but I can't guarantee that and suspect it may have been rebuilt as the float seat looks super shiny. Obviously needs stripping and cleaning before use.
