750 Brawler vs 650 AVS 2 at the track, right OOTB !
Out of curiosity, I looked up the venturi and throttle bore specs of both carbs.
The venturis on the 750 Brawler are 1.38" on all corners and the throttle bores are 1-11/16" (or 1.6875").
The venturis on the 650 AVS2 are 1.19" primary and 1.63" sec. Throttle bores are 1.40" pri and 1.75" sec.
After some quick math, the Edelbrock 650 actually has a larger total venturi area at 6.40 sq. inch vs 5.98 sq. inch for the Brawler 750, whereas the Brawler has a larger total throttle bore area at 8.95 sq. inch vs 7.89 sq inch for the AVS2.
