by Ron Fraser in the September 2006 RootesReview:

I found some additional information about cubic feet per minute (CFM) for Autolite 2 barrel carburetors.

The source is “Ford Engine Parts Interchange”, by George Reid.

His CFM numbers are much higher than any of the numbers I was able to find and I think there is a misprint between the 1.01 and 1.02 venturi sizes.

This is also a good source of casting numbers and Ford parts number for both small block and big block Ford engines. Overall, it looks like a very good reference book.
