milling choke/cfm change

[Bill Baer]

Rod
From what I have read it's not much (2-3 CFM).
However I have read and experienced that a K&N stub stack will help pick up the air flow of any carb especially if you machine it to fit inside a conventional velocity stack.
Note the K&N stub stack does not require any machining,it's a bolt on and will help all by it's self.
Hope this helps
