Chris there was a carb shootout where AED carbs in the small block class won "out of the box" contest and come 2nd overall with "tune" contest.
Now in the big block class AED won both the "out of the box" and "tuned "contest...........thats pretty good going i think, there were about 12 other brands there i think including qft, blp, cfm, braswell, holley etc
All in all there was only 8hp difference between the top 8 carb builders in which AED come out on top in the bb class.
Personally i have a pro systems 4150 carb and im happy with it, my buddy recenctly ordered a pro system dominator 1050 and went to the track where orginal holley 1050 dominator it ran 10.72 best at 124.22mph, and same day swaped it with the prosystem one and ran 10.61 at 125.57mph, then with a jet change it went 10.52 at 126.83mph.
Hope this helps, but i think you will be ok with any of the top brands.
