What did ford do with the 6.7 they couldnt do with the 6.4?
The reason I am asking is some of the techs here might know why ford needed an all new block to get done what they did over the 6.4. does the .3 make that much diff? Or is it just so revolutionarally diff that nothing has been seen like this before.

Not a Ford Tech but here goes. The 6.4 is a Navistar motor, designed buy Navistar. Ford can’t use the exact design, I'm sure patient infringements would apply to some degree, they may be able to use some of it depends on how much input Ford had on it to begin with. It has nothing to do with CCc/CIs although 19 more CIs means about 19 More HP all said and done.

The engines are very different. Just to point out a few areas: High pressure common rail fuel injection, turbo design, inversed airflow through heads, much better cooling to compensate for higher EGTs, much leaner air/fuel mixture

Need to be more specific?
Because it actually was navistars motor,not truely fords..like the 6.7 is.
Well...yes..if they REALLY wanted to get down to it, they could do reverse flow,common rail.yada yada yad...on the 6.4
I believe they wanted a diesel,that was strong,had a lot of room for potential
as in IT IS cheaper to make a REALLY really good design first,then be able to use that platform and build off from it for 10yrs..plus lot less headaches and navistar has given ford headaches,along with the public. Let alone Ford will have a bigger bottom line, the public will be happy with a good motor...FINALLY!!!!
Something that can go along with change as EPA sticks there head further up everybodies *^%,reliable,good MPG,strong,Something to Finally live up to the Ford name..this sums it up right here... it can be around for many years to compete with dodge/gm
The new block for to save on weight and its stronger....they probably got future plans for that block HP/TQ With CGI you can go a lot further on parimeters,than with cast.
NO motor is revolutionary! They just build on it... Still has 8 rods,8 pistons,One crank,2 heads....just some have better components than others (some have 3,4,6 rods,etc)

Reason: Language, next time a point
I wonder if Ford will be selling crate diesels for hotrodders anytime soon? I imagine that a light weight, high HP platform like this could be the new Big Block of the 21st century. We have already seen some diesel swaps into cars for the Duramax but not too many done for the International motors. The 6.7 may be different.

one thing that does worry me about the 6.7 is the aluminum heads. i know they have been around in europe for awhile, but it could be a potential weak point. i sure hope not though.

I have aluminum heads on my VW TDI and the motor has been flawless for nearly 9 years now and 177k miles. I wouldn't give much concern about that.
The EGR trickery, reverse flow heads and turbo heat soaking make me somewhat concerned out of the list of diesel wizardry that I have read/seen so far.

Heat soak is something like putting on an arctic cold weather suit in the tropics. You do not get overheated right away but after a while you get really uncomfortable but you can still function, if you can drink enough water things keep going but are at the limit of their abilities. Things like that tuna sandwich in your pocket go bad and at some point you start to shut down piece by piece.
With the turbo and exhaust manifolds tucked into the valley like they are and covered by all that other stuff, a person wonders if they will build up with heat on a hard pull and also cook everything around them.
I think Ford went in house so they could have an engine designed for pickups not medium duty trucks, so they could make running changes without having to "negotiate" with an out side vendor. The 6.4 and 6.7 are both V8 piston diesels, however, from their construction to their emission controls they are different. Just as the chevy 6.5 and the chevy duramax were different when the duramax was introduced.

I belive this is one of the reasons for the dual coolant/radiator loops

the dmax heads had a few problems early on, but very reliable now....10 years of time tested reliability.
mercedes have been using aluminum heads on diesels for almost 30 years. not without problems of course, but those problems usually showed up after 150,000 miles.
i d say it s the way to go ! !
