Carb ID Application charts?

HI!

Can you guys direct me to a book or link were I can find out what Carb went with a specific car and year based on numbers. Application chart maybe is what I need! I am trying to figure out what alot of these WCFB,s and AFB,s came from so I can hopefully figure out CFM's etc.. ANd trying to build a 50's era correct car! or close anyway! OH is There a way to measure the bore size to figure it out aswell?

Thanks HAMBERS I appreciate you help

Jerry,
I have some old,1960's speed catalogs,some carb O.H.sheets and vintage Motors manuals.AFB's will be easier than WCFB's to ID.
Do you have a list of the numbers?
Just realized the br*** carb.ID tags are gone,correct?The AFB's may be stamped on the edge of the base on some.The WCFB's,missing the tags no way I know.

Those other two are great sites, with a ton of info. Woody

 

Thanks a bunch!!!! I was looking for a pair to figure out cfms so I wouldnt over carb my 331 Hemi I have seen a few good deals but to big for it!

 

If you want to maintain the 'ol time look, use a pair of 57-58 WCFB. They should be around the 450-500 cfm range.

.

 

You can also goole the afb numbers in and most of the time it will show up with the application.
The early caddy afb's make a good choice at 500 cfm each...
Also the early AMC's were 500 cfm as well...

 

so I wouldnt over carb my 331 Hemi

There really isn't such a thing. Read my article: http://victorylibrary.com/mopar/intake-tech.htm

 

That's carbking here on the HAMB's site.

You should call him - he's a great guy, and can put you straight in about 5 minutes!

The question is quite easy, but the answer isn't easy.

Since carburetors in the 1950's were predominently sold as original equipment only; CFM ratings were not published by the carburetor manufacturer (if the car manufacturer was happy, then so was the carburetor manufacturer).

So, how does one arrive at CFM ratings for carbs which were unrated?

If one can find PUBLISHED ratings by the carb manufacturer for some models, then one can GUESS that if the main venturii, booster venturii, and throttle bore are the same on the SAME MODEL but a different tag number. However, this is a guess, as other factors do enter into the air flow.

Example: Carter built about 50 different AFB carburetors for use on Pontiac. WITH THE EXCEPTION OF THE SUPER DUTY PONTIACS, all were built on a 610 CFM frame, but actually flowed from 525 CFM to 610 CFM depending on "air deflectors" such as the one Pontiac had Carter put between the secondaries so that the single AFB'ed GTO would not outrun the more expensive tripower GTO.

And some CFM ratings have been done on some models by other than the carb manufacturer (hotrodders, racers, magazines, etc.).

So is there an easy answer ----- no.
