Holley carburetor

[gitrdone73]

Does anyone know of a website that I can find out what cfm my holley carburetor is.

[aifilaw]

look at the model number stamped on the carb and post it... then one of us can easily answer

[gitrdone73]

6R-3947-B       This is the number I found underneath the air filter

[aifilaw]

There are other stampings on there, I think something like "1850"....
just yank the air filter housing off of there and write down every number you can find separately and post that to be sure.

0222

list     6757

List 6231 is from a '72 Dodge motorhome with a 413, it should have an electric choke.

That's what I have. The guy before me stuck that motor in the car. well that should solve my problem. I didn't think the carburetor was stock so I wanted to make sure it was the correct cfm.
