750 Brawler vs 650 AVS 2 at the track, right OOTB !

I was surprised that two totally different style of carbs, and different CFM ratings could perform so identical right OOTB. The cars build as it sits favors the AVS right now, but as the build progresses, I think the Brawler would distant itself from the AVS
Thinking about installing a hair bigger cam in that engine?
