I was surfing around on a Ford site and some guy there, found a link, that was interesting. If you click the link and read the brochure it says on page 3 that for 2007 the ISB will have in increase in displacement form 5. 9 to 6. 7. This is the best proof I have seen of the rumored 6. 7 Cummins. Anyone else seen this article?
