6.0 to 7.3 swap

Just wondering what it would take to swap a 7.3 in the place of a 6.0. I found a nice 2003 f250 with a blown motor, and wouldn't really want to rebuild it when I can get a 7.3 for cheaper, I would rather have a 7.3 anyways. So my question is how different is the wiring harness? Would the tranny from the 6.0 work on the 7.3? Different pcm for sure. What other problems would I run into? Just seeing if it would be worth it or should I just get a 6.0 out of a newer truck, throw head studs in it and go? thanks

You would need an Engine, Tranny, PCM and complete wire harness for sure. IMO you would be better off getting a reman 6.0 and doing studs and EGR delete

I agree with Dave. Get the 6.0 build it like you want, then stick it in the truck! It will last as long as a 7.3

Sold the truck to help pay $1.5M in medical bills! Now I have a F150 6cyl that is slower and gets worse mileage

You may want to check with your state. Some states have an issue with older engines in newer vehicles. It is mainly for emissions and most states aren't doing diesel emissions checks....yet...,but just in case.

Thats what I was afraid of, not being just a bolt in swap. Also no emission check around here.

Why not do a 12v swap? Cost as much if not less that a 7.3 and easier to make big HP out of? Just a thought

Nothing is out of the question, if I can get the truck as cheap as I hope I can.
