Ok- Just got a remanufactured carburetor from the big carb maker for my 73 newport with all kinds of labels saying it has been tested several times for quality control. So guess what- it is defective. Has a sticking shaft so I am sending back. What is a good source for a carb replacement for a 400 2bl engine? What sources have some of you used with good luck? Any help would be appreciated.

I have a 400 2bbl carb. $40.00. Driving right now, can get you a pic later if interested
Sure- carb running good? Is it a holley or carter? Thanks

I have both. The Holley came off a 360 & the Carter a 400. They ran when removed, but that's been some time ago. I will get you a pic when I get back. If you do end up rebuilding a carb use a good quality kit. The parts store kits are not too good. Carter, Holley or OEM Chrysler. Worth the extra coin

My Bendix-Stromburg on my 383-2 is just about the smoothest idling and operating carb I have ever had the pleasure of experiencing.
It was used literally on a gabillion-zillion Mopar and GM engines in the sixties.
Closest thing you can get to FI in my opinion.

Carter carb
It has a rebuilders decal on it. Linkage works good. Other than shelf dust looks to be pretty clean

Hopefully these come through good

Pictures came through good and thank you. I am going to get another carb from this company first to see if that works. They are trying to make it right. I was against it at first but they really seem to want to do the right thing. If this one does not work I will get in touch with you. I appreciate your help and all the help I have gotten from this website. It has helped me tremendously

No problem. If they will make it right that's the smart thing to do. Let me know if I can help down the road on anything else.

In theory, the best carb for economy & power would be a 4 bbl spreadbore - Thermoquad or Quadrajet. TQ was used on Mopars and QJ on GM's thru the mid-1980's I think. The small primaries give good mixing for smooth idle and good mpg hwy. You would need a 4 bbl intake, but you can get a used Edelbrock on ebay for <$100 and save weight. Swapping the intake is easy on these engines (no coolant), especially if you can leave the metal valley pan/gasket in place. BTW, there is supposed to be a piece of fiberglass sitting below the intake. A good TQ is hard to find today (warped plastic bodies), but QJ's are easy. Often a TQ is "too big" for most engines (~900 cfm), but not for a 400.
I never had much luck with the 2bbl Rochester WWC on my 383 2 bbl, running lean and over-heating the engine. I tried rebuilding myself. I changed to an Edelbrock intake and Holley Pro-jection 2 TBI, but that is another story (works, but quirky).

I am happy with my TQ. It had to have bigger jets installed to compensate for the E10 gas, but works good. I get 10-13 mpg, though (it's a 440).
Your 1973 400-2 bbl was originally equipped with a Holley carburetor. These carburetors, like most early Holleys, were prone to warped castings over time with heat cycling and use. Rebuilders can slap a parts kit on one and claim they flow test it, but when I tried to find one that worked, I went first to NAPA and tried their rebuilt (it didn't work) then went to Autozone and tried there Autoline brand (didn't work) and then I tried their United brand. The United brand was successful and had a smooth idle and launched without a stumble - hit paydirt. I don't know if I was lucky or not finally, but the counter person who I know at Autozone pretty well, said their United brand was the best rebuilder based on returns. So I would try that one given my experience.

By the way, I tried to rebuild mine first myself, but it didn't help due to the warped top piece and I couldn't get it flat no matter what I tried to do. There was a service kit that Chrysler released around 1974 for those carburetors that provided a brace to put on those carburetors to prevent warping - it seems that the wing nut to hold the air cleaner on, when turned too tightly, also tended to warp the top piece. So when you get a good Holley, be sure to not over tighten the wing nut. Or, like Stan said, go to a different brand such as Stromberg or Carter, which weren't as trouble prone as Holleys and are also very smooth like the Holley can be when they are right.
Good luck,
Steve

I agree. It will also keep working when overdue for a rebuild.
Thank you for this info. If my current situation does not work out I will give the United or Bendix a try. Again tjis board to the rescue! Can't thank you guys enough!
