Looking for a rebuildable core?
I have a nice core, but mine is a male carburetor !$20 + shipping

There were 2 different size 1 bbl carbs. In the early years the 170 standard shift cars used a small carb. The 170 auto trans and all 225 engines used the larger carb. Without going to my old books I cannot tell you what years used which carb.
Exactly. I have three or four, but I'm not giving them up. While you can get a chinese knockoff, as I recommended, the OE carburetors are drying up. The knockoffs can be had for well under a hundred bucks. Brand new.

I'm "O-fer" on success with Chinese carbs. Id rather rebuild an original. Even if it means pirating the best parts off of 3 or 4 of them
There's a reason these whole carbs are cheaper than rebuild kits for original carbs. You get what you pay for

There aren't. Not of 1bbl carburetors really and actually compatible with a Slant-6. There are Chinese-knockoff Carter BBD 2-barrels all over, but that's not the question at hand.
There's an Argentinian 1bbl, a copy of a local-to-Argentina version of an ancient (1940s-ish) Holley 1bbl carb. You can bolt it onto a Slant-6 intake, and you can hook up the fuel inlet and the vacuum advance hose, but everything else requires an extreme amount of jury-rig hacking and making do and disabling and going without, etc. I don't consider it a good option, and "remanufactured" carburetors have been a lousy gamble for many years now, but neither is there any other good option except to wait and watch for a suitable NOS (new old stock, that is, never used since it was made) carb to come along on Fleabay or elsewhere. They are scarce these days, and costly when they show up.
(I do have one NOS 1973 Slant-6 Holley 1bbl carb on shelf in Michigan; send a PM if interested.)

There are two different throttle bore sizes: 1-9/16" and 1-11/16". The smaller one was used on 170s (automatic and stick) through '66, and on taxi/fleet 225s (automatic and stick). From '67-up, the 170 got the larger one as well. Taxi/fleet carbs might still have been the smaller size, don't know off hand.
That's just the throttle bore, though. There are many more than two different size 1bbl carbs used on Slant-6 engines, if you count different venturi sizes. Range was from 1-3/8" down to…I think the smallest ones were something like 1-5/32".
But none of this is of much relevance to the question at hand; leaving aside the year/application linkage and hookup differences, any Slant-6 1bbl carburetor will fit on any Slant-6 1bbl intake, and the engine will run and the car will drive. Maybe with a bit better fuel economy with one of the smaller carbs, and a bit better performance with one of the larger carbs.

Dan, Not to be totally picky, but I will beg to differ with you on at least part of your statement. 1964-1966 Valiant 170's with the stick got the smaller barrel and venturie, while the automatics got the same size (larger) carb as the 225's. I do know this from personal experiance from running a 65 Valiant 170 automatic in NHRA "stock eliminator" back in the 1970's. I had many "discussions" with tech officials. They kept trying to disqualify me for running the larger carb, and I had to show them the info in the factory parts book, and the letter from Chrysler and NHRA stating this. But as you said, it is really not relivent to this thread.
You're right.... of course. lol The ones I was seeing were the Ford style, which clocks the linkage 90 degrees from the slant 6.

Y'got me curious, so I went digging, and you're right; I must've been thinking of the earlier model years. Here're the FSM specs for '65 Holley 1920s on US-built cars:
Here're the '65 Carter BBSs on US-built cars:
And here're the '66 US-car BBSs:
So I'll add that as reinforcement for my thing about Slant-6 horsepower ratings.

Just a little FYI. Back the "old days", I measured several of the "larger" 1920's and the dimensions of the barrel and venturi were all over the place. I took one of the carbs and enlarged the carb to the NHRA published specs, and it was a full tenth quicker in the 1/4 mile. Rules said "jets could be changed, but no other modifcation allowed". Was I cheating or not?
Nope. You were legal. That's my story and I'm stickin to it.
