Advice on setting up Dual Carter AFB's....

For a couple seasons, I ran two 800 cfm AVS2 Edelbrocks on a 440. I did not use progressive linkage, I ran 1:1. The setup ran great on the street, and got the 3700lb car (with me in it) down to 11.1 in the 1/4 mile.
A couple notes:
1. Never heard of soldering the idle on one carb - I would not do that mod. You will be able to dial in your idle mix with the AFR gauge.
2. I think progressive linkage complicates things. Keep it simple........
3. Your ignition timing will be critical (like always) but in a dual quad with a bigger intake plenum area, you will need to spend time getting the timing right for the setup. It will likely want more advance, and a quicker curve.
4. Converter and rear end gears to be matched with the above.
5. Don't be intimidated by the tuning. Just make small subtle changes ONE AT A TIME.
