Can you exchange a ford 7.3 diesel with a international 7.3 diesel?

Ummmm. The Ford 7.3L is an International built engine. Ford has used international built diesel engines sense the beginning with the 6.9L IDI up until 2012. The last engine international built and Ford put in their super duty's was the 6.4L. In 2012 Ford said bye, bye to International due to the horriable 6.0L and just as bad 6.4L engines that still have problems to this day and went with a all Ford built 6.7L which is proving to be bulletproof like the old 7.3L's were back in the day.

What is the best Ford diesal engine?

So far, the 7.3L Powerstroke Turbo Diesel V8. But the old 7.3L PSD is running a tight race with the 05 to 07 6.0L Powerstroke Turbo Diesel V8s. They have been proven to be reliable. The only bad 6.0L PSDs were the 03.5 and 04s. Every Ford diesel made has had some good reliability. If you get an upgraded turbo on the 6.4L and a DPF Delete Kit you are good to go for a high mileage diesel. The 6.9L IDI Ford/International diesel was a great engine. Also, the 7.3L IDI Ford/International diesel engine. The 6.9L IDI and 7.3L IDI didn't have a turbo OR great power, but they were great engines. I am liking the new 2011 6.7L Powerstroke Turbo Diesel V8 that is in the new Super Duty trucks. It seems like it will be a very reliable and long-lasting high-mileage engine. There really isn't a "best" Ford diesel now days, but the early 6.0Ls and the 6.4Ls are definetly the pieces of sh*t in this round!
