Six Pack question

I see fuel economy issues as a desire to swap. What has been done to the 750 metering to get the cruise levels correct? If the only thing does has been to change jets, that only scratches the surface.

A 6 pack flows the same air as a true 950 4 barrel carb IIRC. Never seen a 6 pack make the same power as a well tuned 950cfm 4 barrel, rpm air gap or victor.
