I don't know that there is going to be anyone who can give you a magical, 'this is going to work'. But remember your tossing TWICE the shot with the accelerators, twice the pressure drop at the snap of the throttle blades, and twice the headache all around http://www.nastyz28.com/ubb/wink.gif. About all I can suggest is what I'm going to do. I'm starting with a pair of blueprinted 3310's. Patrick wet flowed them at 780cfm each, and pretty much blueprinted them to Holley specs.
If you start with pretty much box-stock specs and read your plugs and drivability they shouldn't be much different than tunning any other motor. Jet down 1 jet size for every 2000' of elevation you are above sea level, then jet the secondaries up for best 1/4 mile MPH. Be SURE and run a balance tube between the secondary diaphrams to get even secondary opening. If you do any street driving I would suspect you will want a pretty stiff secondary spring. The chance of even needing anything more than the primaries anywhere except on the track at WFO is probably unlikely.
BUT, that's just how I'm going to go about it. Your results may vary http://www.nastyz28.com/ubb/wink.gif
