I’m repairing a Quadrajet off of a 67 Impala 327. The carb number is 7037213 with a date code of 2933. It has the newer-style Torx fasteners for the air horn. This would appear to be a service carb built in the fall of 1983. It’s unusual to see no adjustable part throttle system. Any of you Qjet folks ever run across this? I don’t recall if they wet-flowed service carbs back in the day. One of the important adjustments for production carbs on the flow bench was APT. Service carbs got a pass or that wasn’t part of the calibration process I suppose.
