Not sure how you can tell by a picture how much a carburetor flows. I can assure you with first hand experience a 1.39 venturi could flow similar to what a basic unmodified 4781would flow. The Edelbrock carburetor's offer a lot of nice upgrades. Hopefully the Internet BS'ers don't kill it.
Edelbrock ingeniously increased the flow of the basic Q-jet design and most folks (including some "experts") look right past the obvious modifications that gained the flow and say it was just an advertising gimmick..... Chit has changed a lot since Holley sold their first 4781.
