So I layed these two side by side because a picture says 1000 words. While I had them out I did a quick gage of the L W and radius of each at the port opening so I could calculate the cross-section. This is a 460 Predator beside a 440-1 Indy cnc'd by Modern. At the opening the MW has a larger area! 3.36" versus 3.16" Obviously it doesn't tell the whole story.
