Buggin' me (carb ?) - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I was talking to my friend's dad about 305/350 2barrel/4barrel, and i said something about "at least with a 2 barrel carb I'm getting better gas mileage than a 4 barrel". He said that was not exactly correct; a 2 barrel carb has 2 medium sized holes and a 4 barrel has 2 small holes and 2 large holes, and as long as you don't flog on it you can do just as good with gas mileage. This true? This is just a "curiosity" question, as i don't plan on changing my manifold ever, just wondering if his logic was correct.
