Will any Mopar slant 6 1bbl carburetor fit on my 1968 225 1bbl slant 6?
Thanks,
Al in Maine

About the only slant carb that you would not want to use would be an emissions carb that has electrical wires in the area of the float bowl. That would be mid 80’s vintage.
I don’t know much about single bbl slant carbs, I believe there are:
Holly 1920’s and 1945’s and Carter BBS. There are probably others.

From my experience (a 225 69 engine): I think all can bolt in, but they are not necessarily a good choice...


1- As DadTruck said, avoid ones with cables (for the Lean Burn setup), early 80s

2- They might have different venturi and jet sizes depending on the year and application (170, 195 or 225 Cubic Inches). This should bring some changes on your performance, it might be preferable to find one for your engine's displacement (at least)

3- More vacuum ports will come from newer years. Be ready to plug them (I did with rubber caps). I'll recommend you have a copy of your service manual and of the carb's year you are adapting, so you see what has to be plugged.

4- Linkage: you have a cable accelerator linkage. Old carbs (1965) have mechanical linkages and the carb connection is made to link to it, you might be able to make then work for your application, but more hassle.

5- Some carbs are better than others on different areas (The Holley 1920 is good but the float is made of foam, hard to find. The Holley 1945 float is made of brass, but some people that carb is harder to make it to work fine (but a so so working carb is better than a no working one). The Carter BBS is good from what I have seen.

6- Some hardware you might need to move from the old carb to the new carb (i.e. dashpot and bracket if you have a manual transmission)

7- Avoid copies/new manufactured carbs, and recently remanufactured carbs from big stores (carb might be crap). Try old remanufactured ones or NOS... every now and then you see them in ebay. SlantSixDan (member here, has a stash of carbs, you can check with him, if you want).

8- Repairing your old carb is usually a recommendation. Install shaft bushings if there is too much clearance there, and rebuild them. People have done that here. In the worst case scenario you have a carb that does not operate 100%, but you know the origin.

Some things to ponder about, Good luck.

PD: By the way I just noticed you have a Satellite... B bodies pulled by Slant Sixes ... only for the brave and patient! (but the car will reach the requested speed eventually). Good to see somebody else in the club!

just a dumb, kind of related question on carb choice.... I wonder if a Carter YF would work on a slant.... and have sometimes wondered why Mopar never used that carb on a slant.... I had worked on a few of those back in the day and they seemed like a decent choice..... might have to adapt a bit for linkage and such.

where's mavtv91?

He is a Guru with these trivia show questions.
