850 bg vs 950 prosystem

will a bg out flow a pro 950 carb which flows 830 wet flow , the venturi and butter flys are larger on the bg i think the same as there 1050 , i spoke to pro systems about modifying to 1050 they were more interested in selling me the sv 1 carb any ideas

I've posted this before but, my BG Mighty Demon 750 flows 950.7 CFM dry.
My Pro Systems 950 flows 964 CFM dry.

BG 750 also outran the 950 in several back to back tests. That doesn't
mean Pro Systems are bad, just my limited experience.

thanks so a 850 bg might flow 1050 cfm next time out will try one back to back
