I spoke to the Navistar plant manager when Peggy and I toured the engine plant in August. He was bragging about gearing up for 6.4L production and the expense of the engine (citing the 4 EGRs as an example). Its essentially the same engine block produced on the same line by the same company. This is still Navistar's project.

I was under the impression that the issues with the "early" 6.0's were issues with Ford's software programs (however since worked out), not the Navstar engine. This holding true for ALL newer high tech engines to meet the latest EPA regs throughout the diesel auto industry as well. Am I mistaken? Also, I thought the 6.4 was just going to be a modified 6.0. Now I am hearing that the 6.4 will be manufactured by Ford and not Navstar???

I'll defer to Ken's sources over mine. It wouldn't surprise me in the least if I was told that just to see how long it got out into the public, and who's saying what. You'd think I'd learn from the number of times Ford has burned me on the "this-is-what we'll-do-NEXT-week-for-rebates" info.......

i see no point in having two VGT's when the purpose is to get away from the VGT design and have a small turbo for low boost/fast response, and a big turbo that has no lag, due to the small turbo "pre-spooling" it.
