The Urea reacts with the compounds in the exhaust. Both effectively cancel out. You will not be killing anyone when you drive by. Ford did not screw up anything, emissions mandates are forcing them to change.

Sorry for being so igorant. The way I understand it is Ford and International have screwed up the Powerstrokes so bad no one will buy them. Any thought to that. Now they are changing the whole design, then CAT and International are going together and will change the whole design and Ford will try to copy it. I am buying a GMC next time. I drive one haouling a 35 ft horse trailer and with 3 Belgians weighing 2000 apiece and a hay wagon, it will walk off and leave my 7.3 with a trailer and hay wagon in VA. Will keep this 97 PS but I'm done with Ford. I'm sure the Kingdom of California will come up with some reason Urea can't be used, like it's not manufactured there. 
GOSH Sorry I had to rant. I have ahead cold.

The 6.4 would do the same as that GM to your 97, Ford is not copying what International will be bringing to the table next. The 6.4 is a strong motor, were all hoping the 6.7 from Ford will be even stronger. The biggest thing is EGR, International is using strictly EGR to meet the emission mandates while pretty much all other manufactures are going the UREA/SCR route which if it works like they say should bring the mileage back up in the diesel world.

Unlikely, the biggest hit to mileage is from the DPF, which requires fuel to be dumped into the engine to burn the soot off.
@Passin-Thru, Ford still sold more 6.0s then duramaxes, and I bet they are still selling more 6.4s as well. Ford never designed anything on the 6.9/7.3 IDI, 7.3 PSD, 6.0 or 6.4 PSD. They simply bought the engines from international. The only reason ford ever dumped the 7.3,6.0 or 6.4 for that matter is because of emissions regs.
The 6.7 is not related in anyway to international, it is based off a Land Rover V8 diesel. Ford has no reason to copy International, since the engine is already developed and has been seen in working trucks.
California will not ban Urea, its needed to easily meet 2010 emissions, and it will not pollute any if it is being used properly - ex. not dumping it on the ground next to your car, instead of putting it into the car.
As for the Duramax being faster then an old 7.3, thats a given, newer enigne, more power. Same goes for the 6.4, its got much more power then a 7.3

The oil filler caps on the 7.3-T444Es,6.0-VT365s,6.4-MaxxForce7s are sourced from Ford
and why do the ECMs and IDMs on my T444Es have Ford part numbers?

As ford the IDM, it has a Ford part number the same way the top of the engine is labeled a "7.3 Powerstroke". Just ford sticking their own sticker on it. The PCM on the fords are different to accommodate full OBD-II and other truck control systems. But the the engine it self is no different

But the top of our engines don't say "7.3 Powerstroke", they say "T444E" as they are in International school buses.

Not the valve cover sticker, the little plastic engine cover that ford throws on.

I believe the freeze point of DEF (Diesel Emissions Fluid) is right around 20 degrees, but the EPA is allowing a period on non-compliance while the fluid thaws via on-board heating...
