Identification of virtually any original equipment carburetor (up through the 1974 model year) if fairly easy, assuming you have the carburetor identification number. To do so:

(A) bring up your favorite search engine (we use google)
(B) type the following string:

"Carburetor Shop" bbbbbb nnnnnn
where bbbbbb is the brand and nnnnnn is the number
in this case the string would be

"Carburetor Shop" Rochester 7029244

This will bring you to an applications page on our website.

From there (assuming you are using Internet Explorer) click the "Edit" pull-down menu, and "Find on this page" and enter the carburetor number. This will take you to the exact listing.

In the case of the first example, one must add the 70 to the 29268 resulting in 7029268. The string for this number would be:

"Carburetor Shop" Rochester 7029268

It is well documented in many places on the internet where some of the 1969 Rochesters were stamped without the 70.

In this instance, the additional information of casting numbers proves that the castings have been interchanged from different carburetors (this information is not on line).
