I bought a GS400 with TH400 several years ago that came with several different Quadrajets. It had the original engine out of the car needing a rebuild and a fresh 455 in the car. I have since rebuilt the 400 and plan to return the car back to numbers matching status. Can anyone help in identifying which of the carbs is correct? Thanks
The '67 will have an angled fuel inlet (similar to Chev's) and the part number will be on a round medallion rather than stamped in the housing. These are unique characteristics to the 1966 and 1967 Q-Jets.
