L79 carburator

We are trying to find a carburator for an L79. We don't need the 'correct' carb, but would like to use one that will work satisfactorily, either a Holley or a QJet. Can anyone tell me what the CFM is for the 68 L79?
The 'Holley' that we have is a 750CFM that needs rebuilding and is way too large.
I started this thread earlier, but accidentially posted it to the C6 area. Didn't mean to, but....
Thanks

here is a link on the history of the L79, the article says 585 to 600 cfm

The 750cfm that you have, vaccuum secondaries or mechanical?

Vacuum and it is junk in its current condition. We will rebuild it and keep it.

Thanks for that. I seemed to remember it being 585 or 600 depending on the source.
