Doesn't the relationship between the throttle body and venturi size have a lot to do with it? The amount of signal strength your boosters get, etc depending on throttle body size?
Yes. But the Venturi diameter is the biggest influence for performance and driveablity. And the shape of the main body. Look at the Holley junk we had when I was young. That idiotic choke tower was in the way. I was milling those off in high school. And it still sucked because you still had that huge square, flow killing area around the primaries.
That's why I say don't get locked into CFM rating. There is so much more to it than that.
