Technical Carter WCFB carbs, which one?

Hello all,

I have an odd ball situation. I'm trying to determine the best Carter WCFB for my car. Long story short, my car is a 58 Dodge Coronet with a 325 in it. At some point in it's life a previous owner swapped the stock poly heads for hemi heads. I'm not sure what else was done to the motor when this happened but it is what it is and trying to go back to a poly would be costly. So I live with the hemi, which I don't mind at all. Now the problem is my current carb is a Carter WCFB that needs some help. However it's missing the br*** tag so I have no idea which model it is. Before I rebuild the carb, what I'd like to do is make sure I have the correct carb for my application and then worry about getting it rebuilt. I've spoken with some people who deal with the FL Mopars and I was given a few different Carters. I don't know which one would work best. Any help would be greatly appreciated. Also, maybe I have the correct carb now, I just don't know what model it is, any ideas would be great.

Here's what I've been told, and please note the reason why I'm listing the 57 Coronet is because that's the year Dodge had the 325 Hemi even though my car is a 58 (I know, confusing)

1957 -D67 package - Carter 2532S
1957 -D500 package - Carter 2622S (I think this is the one I need but I'm guessing)
1957 -D500 Police special - Carter 2698S
1958 -LD-2M - Carter 2660S (This would have been my stock carb as I have the LD-2 package)

Thank you,
Sam

 

Carb king will chime in here but the one for the D500 sounds right. I thought by 57-8 MoPars would be using the large base WCFB’s with the exception of dual quads. Are you sure of the intake. Just asking to make sure as I looked at a lot of small base Carters..not an expert.

 

No clue on the intake but I ***ume it's original

 

Just looked at a video by google of a single WCFB on a restored 57- D 500 and it definitely had a small base. if all your linkage works and looks correct there may not be much difference. Carbking knows the Venturi size differences on single and dual quads and which numbers are correct. If what you have runs good and I would not worry too much. Even the rebuild kits cover many different car manufacturers. Carbking has a website.

 

A couple more pics of my carb for reference. It works but needs a rebuild.

 

Two people have suggested you contact carb king. I'll make it easy for you.
His name is Jon
His website www.thecarburetorshop.com
His Hamb handle is @carbking

 

I will, he doesn't open until Tuesday, but I'll reach out to him then.

 

2698s has the rectangular base, the others have the older almost square base.

Since the other 3 were calibrated for the 325, you can probably use any of them.

Get the number(s) from each of the metering rods before you call.

Jon.

 

Thanks Jon, sure I can do that.

 

Hello all,

Just to give a quick update, first, thanks to Jon @carbking for the advice this morning. It gave me some good points to start with. I was working on the car a little today between meetings and tested the choke. It's working, but I think I have a mismatch. The choke part number is 170AU 456S which would be the correct choke on a 325 hemi with the 2532S carb. Jon was able to determine that I most likely have the original 1958 Carter WCFB 2660S in the car. My question is, will this mismatch of choke and carb be a problem?

Thank you,
Sam

 

Sam - as long as you can adjust it as I mentioned, it should work fine.

Jon.

 

Awesome, thanks again Jon!

 

Hey all,

Just a quick update, my choke was completely out of whack. Between the linkage not being bent properly for the phelonic spacer and the fast idle cam being in the wrong position, I got a world of hurt with it. On top of that Jon mentioned I should check my choke to see if it still works, it doesn't, but luckily I found a NOS on ebay so hopefully I'll have that in a few days.

Thanks,
Sam
