6 Pack vs. 650 4BBL?

As I've said before, if you use a 3310 and it's faster it's a tune up problem. Most of the time the secondaries don't open, or barely open. Might as well use a big 2 V carb.

A 3310 is a boat anchor. Don't waste your money on ANY vacuum secondary carb. If you are going to spend money, call BLP or mark Whitener or thumperdart over on moparts.

Quickfuel is now owned by Holley and it shows.

Spend your money once. No vacuum secondaries and a tune able carb. Air bleeds and idle feed changes are simple. I have faith that you can learn it if you want to.
