The 2.8 Duramax and 3.0 power stroke have been around a long time overseas already. The power stroke is changed a bit, but it has been made by Ford for land rover applications for some years, the first ones had big problems with failing oil pumps and breaking crankshafts, if you look up the discovery 4 tdv6 that's what the engine was, but I understand that Ford changed the crankshaft and a few other things to make the one they have now.
Personally I kinda wish they put the 3.2 i-5 engine in the pickups, I've heard it was pretty good.
The 2.8 Duramax has been used in the isuzu kb280dt overseas for years. I used to drive one of the older ones, and it was a tough engine and ran great!
