All I can do is post some pics that I found (some from here, some not) that might help to highlight some of the differences. I don't claim to know anything about intake design; I just like to sawzall on them where it looks to me like they need it. scope

Here are pics of the TF 440 intake, followed by pics of the Victor 440 intake (including the plenum mods that I've done on my own), followed by shots of a stock Super Victor 440 and the Wilson-modified Super Victor that AndyF has.

At some point I may be in the position to test a TF, but it wouldn't be against an out-of-the-box Victor... 'cuz I can't leave 'em alone. whistling
