I did this swap back in 2016 and have driven it 15k miles. I thought I would post some info and my experience. This swap was fairly easy and many people have done it in these older fords. I purchased the engine off of Craigslist it is a 2001 4bt out of a lull fork lift. It has the industrial bosh a style injection pump and governor. I also purchased a zf five speed off of Craigslist out of a 1990s f250.
