KenC - First let me tell you that I cannot recommend the Holleys (Holleys don't like me, they all seem to think I am a practicing fireman!!!); but I won't try to talk you out of them.
If we were recommending some real carburetors for your application, we would suggest a pair from O.E. engines of about 200 ~ 215 CID.
As to the Holley list numbers: we bought the booklet from Holley that has "all" Holley carburetors, as we manufacture kits, and thought this would be a great reference, however, we have more than 1000 entries of Holley applications in our database that were NOT listed in the official booklet.
Eventually, we will get our entire database published on our website, but it takes time (currently more than 100,000 applications). In the meantime, simply try using Google with 2 search strings: The first "The Carburetor Shop" and use the quotes, the second the carburetor number. If we have that number published, Google will bring you to a page on our website. Open that page, and then use the "find" command in your browser (under "Edit" in IE) and enter the carb number without any prefix or suffix.
Example: if you have a Holley LIST number R-2418-AAS then use this string:
"The Carburetor Shop" 2418
This gets you into our site. Now use the find command and enter 2418. This takes you to a line that says 1962 Dodge 225 Holley 1920.
Virtually all passenger applications from 1897 to 1974 are currently published. We are currently working on tractor listings. Once the tractor listings are done, we will switch to trucks, although we have already done the more common trucks. You can easily identify many carburetors using this method.
Jon.
