From the ones I have seen, XE are the same as XD. I always ID them from the Thermoquad number stamped on the throttle base plate at the back of the carbie.
XD/E
9144S - 4.9 auto
9143S - 4.9 manual
9142S - 5.8 auto
9141S - 5.8 manual

XC
9091S - 4.9 manual
9022S (or 9092S) - 4.9 auto
9071S - 5.8 manual
9085S - 5.8 auto
Some XC numbers differ depending on where you get your info from.

Chrysler also used Thermoquads so if its not one of the above numbers it may be a Chrysler one.

There was also 2 different sizes for the primary throttle bore. 1 3/8 inch and 1 1/2 inch. The falcon's only got the 1 3/8 inch. If you have one of the "bigger" 1 1/2 throttle bore carbies, hang on to it.

There all 1 3/8" primaries and there all off fords.(motor craft tags)
The two so far i cant id are #9533s and #9333s.
I have found a website that states the #9333s is off XE4.9 Auto whether this is correct or not?
F100 Maybe? Its not that important but i record all numbers when i strip them down and these two carbs are the only two that have had the #370 squirters! All others for autos are #369 and manuals are #374.

What code do those 2 (9533S & 9333S) have on the Motorcraft tags? I have never really taken notice of the squirter numbers as I drill them oversize anyway.
More important is the number on the metering rods. Have you recorded these?

From memory the XC Thermoquads are 76DA....... and XD/XE are 78DA...... I tend to agree with your F100 theory, especially as they are richer in the squirters and only the power step on the metering rods. That 33 on the rods is a bit richer on the power step hey.
Good to see someone else who knows their way around a Thermoquad.

No that theory doesnt check out. I found a listing for rod sizes in relation to id tags on this website(see attachment) and according to it f truck tags all started with 80 not 76 or 78 and these have rod numbers that i have never seen before.
You will also note the absence of the 2174 rod which appears to be the most common?I would say this listing is for only one model year possibly? 76DA TAGS come on everything and anything! e.g. 76DA KF is xd 302 manual,so is T6DA KC? 76DA ND is XD 351 Auto. There seems to be almost no consistency with numbering what so ever?
Out of interest the rods i have are
#1998 * 1 pair 70-57-40 (Came out of carb 9144s 4.9 auto)
#2173 * 1 pair 72-57-40 (Came out of carb 9142s 5.8 auto) Which is bolted to my genuine/origional jan/1979 p6 town car xc era?!
#2174 * 7 pairs 70-55-38
#2354 * 3 pairs 70-55-33

The 2174 are .002" smaller on all steps compared to the 2173 which is supposed to be fitted to the majority of vehicles by the look of it ? A common mod back in the day maybe?
Yes i do like the tq . Rebiuld em drill the sec jets, set airdoor properly and away you go!

This page has a handy rod size reference.

Its getting harder to find good core stock of these carbs now, anyone have any to give to a good home?!
Good carbs if you spend time setting them up properly. I used to do a lot on them years ago when time was all i could afford on my own stuff to make it go better, once I got money I went to Holley carbs for ease of parts etc and because thats what customers wanted but at the end of the day in most cases I cant say that the holley is any better when compared to a well set TQ. TQ's are a bit of an ugly duckling , I think thats why most go for the holley stuff, nothing a big air filter cant fix!

I know this is an old thread but if anyone is still interested the 9333s does indeed come of the F100.  I just bought one from a gentleman doing up an F100 who wants to put a Holley on it.  Interestingly the 2354 metering rods referred to above came out of this carburettor and as noted the power step is .005" smaller in diameter than the 2174 so I'll be putting those metering rods back in to my interceptor to see how they go.  Cheers from a Newbie.
