Myths and realities of carburetor sizing

I like Uncle Tony...however, he does get too long winded in his videos. Cut the babble and go right into the topic would be my suggestion. That said, he is correct. He mentions the good 'ol ignorant street squirrel's "Your gonna flood the engine with gas!" on large or dual car'b applications. Vacuum determines the 'flow' of air on a carburetor's output. You can install a Holley Dominator on a stock small block engine. It will run...however, the throttle response/velocity/drivability will be horrible.

         DANGER, DANGER!   

         "Cut the babble",  then it wouldn't be a two minute video!   

         And: " Vacuum determines the 'flow' of air on a carburetor's output."  Well, I think it would be better said that "vacuum", or better described as just the pressure differential presented at the critical junctures of the carburetor 'determines the carburetors' flow of fuel output', which is really what "carburetion" is all about; "throttling" of the atmospheres' ingress into the engine and the resultant "vacuum" created, as generally referenced, is a different subject; though there are certain observed relationships involved, but this has more to do with shortcomings in the mechanics of the device.   

         Hence, why E.F.I. has displaced the mechanical carburetor in typical automotive O.E.M. production.
