What is the CFM rating for a Holley two barrel for a 1964 pickup?  Also, were there any different ratings for earlier models?  Thanks

Cactus,

            I'm not exactly certain, but there will be a "list" number on the air horn. You can usually cross reference that to the Holley site. It's probably in the 200 to 250 CFM range.

Thanks, I have a couple of them off of motors that I have, and could not find the numbers.  I was just curious as to what capability they might have.

All of the 60 - 64 trucks I have seen which have stock carbs have the Autolite 2V with 1.02 venturis, and a CFM rating of 245.   They are similar to Holley 2300s.
