I’ll add this to the info already posted regarding the ’55 Holley 4V carbs.  The Teapot carb number for an early production (Dec 1954) 182HP Special 272 would be Ford part number ECK-9510-D and Holley List 957-1.  The Holley manual does list this carb for a 292 with no mention of a 272.  Going to the Ford parts catalogue for the era shows both the 1955 4V 272’s and 292’s sharing the same list number 4V Holley carbs.  In looking through the Ford parts book, I found no fewer than three different carbs available for the 182HP Special during 1955.  The earliest carb (List #957-1) covered 4V equipped 272 engines installed before Dec 27, 1954, while the second carb covered engines installed between Dec 27, ‘54 and April 12, ‘55.  The third carb covered 182HP Specials installed after Apr 12, 1955.

Thanks a lot Ted for the info.  I took the carb over to a friends yesterday to help with the rebuild.  It was a terrible mess having sat without the aircleaner for decades, but with hood in place.  Mud wasps had completely filled the space between throttle shafts and choke blades.  Ants had built their own house in the float bowl.  After clearing all the junk out, all the shafts were nice and free.

The old 4V came out well:
