Need help tuning AED carb

Thanks for the link. I will be calling them Monday first thing. One thing crackedback mentioned was to check the afr with increasing the rpm. I did notice yesterday when I hit the interstate to get some speed up for 3 miles or so that at 70 mph the afr got better. Then I push the pedal on down a good ways til it hit 90 or so then let off. I noticed that at that speed the afr was in the 14's. But the secondaries were being used at this point.

You are going to have to make a few changes to that carb to get it right for street/strip performance.
Smaller IFRs to get the idle/cruise leaner. You probably have .033 IFRs it it now and need .031 or smaller.
Larger PVCR to get 12.5 WOT with 66/80 jets.
The 5 emulsion hole metering blocks IMO are over kill. Look at the old holley metering blocks and they used 2 .026 or .028 holes and work great. I've set up all the 650 and 750 carbs I've run with that set up using a .029 - .030 MAB and they cruise at high 13 to low 14 on the highway and mid 12 WOT. The WOT curve is very flat and stable.
