The name "Powerstroke" is owned by ford, it has nothing to do with IH/Navistar. Every diesel until the 6.7 was an IH/Navistar. Ford severed ties with IH/Navistar over warranty issues and overall lack of quality and durability with their engines (mainly the 6.0/6.4) this caused Ford to develop their own engine in-house, also which none of their competition has done yet.
Here are some of the new things and unique features about the 6.7.
-High pressure (30,000 psi) common rail/Bosch injection system, not the HEUI high pressure oil system.
-Single/sequential turbo setup, One turbo with a single exh turbine, and dual sided twin compressor wheel and housings, this basically operates like twins.
-Reverse flow 4V cyl heads. Intake ports are on the outside of the heads and the exhaust ports are inside the valley.
-2 totally separate cooling systems. 2 radiators, water pumps & reservoirs. Primary cooling system is for the engine only. Secondary cooling system is for all the coolers ( CAC, EGR, fuel, trans)

The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
