QUESTION: How do I know if a vacuum or mechanical carburetor is best for me?
ANSWER For street cars the vacuum secondary carburetor works best on midweight or heavyweight cars with an automatic transmission. They are more forgiving than a Double Pumper is because they work by sensing engine load. The mechanical secondary carburetor is best on a lighter car with radical camshaft and a lower gear and manual transmission or on a car that is going to be used for racing purposes.

Huh. I know plenty of people that do it (usually with 3310s) - but their cars aren't too radical. Did you ask Holley about carb sizing as well? I'm interested in what they say.
