Holley 1-bbl carb application?

[greenie]

Interesting Holley carb found at swap meet. It is marked: 6R, and stamped 1951B. Any idea of its application(s). 
Thanks!

You need the carburetor identification number, and then use the search engine of your choice with a search string of:

 

Holley thecarburetorshop.com [then add the list number without the prefix and suffix here]

 

Don't use the brackets.

 

To get the identification number, assemble:

 

(1) A wire brush

(2) A pencil eraser

(3) A strong light

(4) A strong magnifying glass

(5) Most importantly, a pair of young eyes

 

Once you have all of the above:

 

(1) Orient the carburetor such that you can read the word "Holley" on the bowl.

(2) Note the fuel inlet is to your left, and screws into a square "boss" that stands proud of the rest of the body.

(3) Using the wire brush and pencil eraser, clean the side of the boss that you can see

(4) Read the identification number.

 

There are a number of types of numbers, as the O.E. number will be stamped first; but you are interested in the Holley "List" number.

 

An example might be ECZ-9510-AA List R-1434-A

 

In this example all you are interested in would be the 1434

 

Now you can find the application.

Old Ford six....223?

Thanks for your help, Carbking. With numbers all over the carb, it’s the well-hidden ones that matter. In this case, the list number is 2042; and the part number B2AE 9510-A. All this means it belongs on a ‘56-‘57 Ford truck with the 223 six.  Thanks!
