I have a Set of Carter Carburetors and i was wondering if someone could tell me the specs on them. only one of them have a tag on it and the #'s are as follow: 3815403 3361S the other carb doesnt have a tag but its on old dual 4bbl offenhouser intake. if anyone has any info id greatly appreciate it.

 

Sounds like my old setup off of my 56.
First, a couple of questions, Do the carbs have a bunch of vacuum fittings on them, or are the bosses for the vacuum fittings NOT drilled. If they do not have vacuum fittings the carbs are probably Carter competition series.
If the carbs have 2- vent tubes going over the top of them and tiny bores, then they are probably Carter WCFB series from an early vette. (these might be hi $$$ carbs).
I'll keep surfing, dual quads are very cool sounding BTW.

I founf this, hope it helps:

The other carb is a 3804 and it seems to be a little different it looks to be a double pumper and it also has a choke on it. but here is a pic of the setup hopefully itll help you help me figure out what they are.

 

also the 3804 is mostly apart now someone previously took it apart and i have all the peices.

 

There's no double pumper AFB, the carb with the choke (best I can tell from the pic) is the rear carb, the car basically runs off of the rear carb-primaries duirng idle and warm up. The linkage is progreesive so you get carb-2 primaries, carb-1 primaries and then the secondaries come in on the vacuum. I'm guessing that those are somebodys factory carbs on an aftermarket Offy manifold. Believe it or not, I've rebuilt carbs that looked worse than that and they ran great. (don't try it with a Holley).
Wild guess-They're 500cfm

 

Well i just checked into it on e-bay and they have one with the same 3361s and it says from a 62-64 impala SS and the other is a 3804S not a 3804 and im not sure if its from the same car. i called autozone and rebuild kits are 20 bucks for a 64 impala with the dual 4's

 

Assuming that the one has a choke on it, I'd guess they were from the same car. They usually had 2 carb numbers, 1 for the primary (choke) carb and one for the secondary carb. Maybe a 409?\

dude, you're there 435HP 409 both carbs. Some poor resto slob would probably give his first born for those.

 

WOW! thats nuts i got the whole setup for like 75 bucks. wow that is crazy i saw a rebuildable one, same type for 100 bucks for one rebuildable one. hmmm

 

Too bad you didn't get the original intake!

Anyway, don't butcher those carbs. If you need to go buy some new Carter AFB's and store the old ones.

 

Ill probably offload these ones and get some other carbs, they would be worth more to someone else than me right now, i could use them but id rather see someone finish a resto or something like that.

 

Glad I could've been of assistance.

 

yeah thank-you very much for your help, :yourock: lol
