Air filter assembly does not seem to fit on my 292

[zuburg]

The saga continues. I’m wondering if there are different (but similar) air filter assemblies for Teapot carbs on a 292?

The one that was in my 1956 Thunderbird is hitting the heater control valve on the intake right in front of the carb, preventing the bottom section of the air filter housing to lay flat on the carb. You can see where the previous owner has hammered a dent in the bottom housing trying to get it to fit (not works ). I believe they also hammered in some dents on the side to help clear the choke.

Does my picture look correct for the Teapot carb and heater control valve? (I wonder if the carb came from another car or truck and is not the same as a Thunderbird?)

Are there different air filter housings for a Thunderbird that would clear the choke and heater control valve?

its may be from a 55 as the choke was in the intake itself so set lower.

The original air cleaner housings for '55, '56 & '57 T-Birds are each year specific to match the carburetor(s).
The '56 oil bath housing has a raised area in the bottom to clear the carb mounted choke thermostat housing
(left side of photo 1) not sure about the heater valve clearance.

As far as I know, the air cleaner housings with the cork lip in front were only used on '55/'57 T-Birds.
The one you have that a previous owner hammered on was likely the '55 version.

I have a list of the 'correct' teapot carb numbers for '56 T-Birds that I'll add into this reply as soon as I dig the book out. The number is cast into the lower rear flange. Example, photo 2

(edit)
From page 60 #85 of the big red CTCI T-Bird restoration book...
The various carb numbers for a 312 auto trans: (if I'm reading the paragraph correctly)
ECJ-Y, List 1164-2 ..... ECJ-N, List 1164 ..... ECJ-V, List 1164-1

The various carb numbers for a 292 manual trans:
ECJ-Z, List 1163-2 ..... ECJ-R, List 1163 ..... ECJ-V, List 1163-1

I'm unsure of the differences in the carburetors for 312 or 292.
A visible difference in the carburetors for automatic or manual transmission would be a dashpot for the throttle lever, to help keep it from closing too quickly. Photo 3, yellow circle

I think you are right, I think I have a 1955 air cleaner. The funny thing is the previous owner beat the heck out of it to put a dent in it to clear the choke. I was able to fiddle with it to finally get it to sit OK (I also tightened the heater control valve one complete turn). The way I got it all to fit decently and tighten down with the wing nut was to not use the piece in the photo that was under the dry filter element. Also, I bought a new carb stud that fit tighter than the old one (which was probably also from a 1955 (slightly smaller bolt size). I have quite a lot of the stud sticking above the top cover. I assume it will be OK to cut that down?

All of these carbs were used on 292 and 312 engines in '56. The calibrations are the same between the auto and manual trans carbs. Like dmsfrr said, the only difference between the auto and manual carbs (besides the part number stamping) is a dashpot and bracket on the auto trans carbs (LIST 1164).

Yes, no point in getting a new upward dent in the middle of the hood scoop. Screw the new stud into the carb as far as it will go easily. With the air cleaner on measure how much of the stud is extra, just above the top of the wings on the wing nut. Take it out of the carb and cut off the excess.

And an extra check ball in the base of the carb as I recall...

The small plastic check ball that was used to regulate the vacuum for the Loadomatic disributor, was last used on early 1955 carbs. For some reason, it was used in the larger 1956 Lincoln teapot carb though.
