Danny,
While you are at it, could you clarify to the best of your knowledge what is or is not allowed as far as booster modifications to Holley carbs, specifically the 3310 type used on Ford and Chevrolet products?
If not you, anybody else? And could you say what the CFM differences are by swapping boosters on a Holley while remaining "legal"?
