I was talking to my ford dealer yesterday, one of my service guys confirmed, fords dropping the 6.4 after two years in production. the 2010 trucks will have a FORD diesel in them. theyve kept it in good disgize...(man i have no idea how to spell that word. i hope you guys can sound it out...ha!) but anyway, he said the ford diesel has been around since 06! so that engine will have a good 4-5 years under its belt before its released. it will be interesting to see what will happen with them. it seems the 6.4 is getting worse with age.
