I doubt the 1000 HP I6 in Austrailia shares anything with any of the American I6 ever prudeced. We can only hope that, some time soon, Ford will bring some of the cool Ausie. stuff here like the 400 HP 5.4L BOSS and the turbo I6. The 500 will get old fast if they don't put some muscle in it soon.
probably not. A lot of stuff from the 60's did. One guy I know of was able to get aussie crossflow head to work on a us 250. I'd like to see the european turbo I6, it was a concept but was about 180ci and made like 350hp.
