'73 Oldsmobile automatic built on the 180th day of '73 Source: http://www.cliffshighperformance.com/tech_carb_ID_2.html
I would also add that the 73 Old's unit is a hot air choke model, small casting (750cfm), and they still use the 68 and older float/fulcrum arrangement. It is NOT a viable replacment for a Buick q-jet from the same period, the Buick units are superior in many respects, and many 71-74 Buick units are the larger castings......Cliff
