Anyone know ifit's been done? I had an enquiry today as the guy's 7.3 Powerstroke expired....

Any feedback appreciated.

I keep trying to talk my uncle into doing exactly this. He has a gorgeous 1997 F350 with the 7.3, but the 7.3 just won't die. If/when it does, he will probably go for it.

I really like the way the older Fords looked.

More on topic, if you have the money, Destroked will most likely be able to hook you up.

Thanks for the input. Is Destroked a business or someone on here?

Thinking that the wiring harness would be interesting....

Destroked is a business. You could always ask around with local shops, because a good shop would be capable of doing the swap as well.

Thanks guys. I am in Australia, not many shops over here...yet.

Any leads on what model engine is the best one to use for a swap, and where I could locate one complete with wiring harness, ecu and trans?

Any of them. Most parts inner change with each other.
LB7- no emissions really to speak of, but injectors are under the valve cover and they last about a 100K ish. Best stock pistons
LLY- Just a EGR. Same pistons as LB7. External injectors, easier to R&R.
LBZ- EGR, Stronger rods than the previous engine but not that much stronger;), Pistons are a crap shoot if they will crack or not:D, arguably the best performing engine for the least amount of effort.
LMM- same as the LBZ engine, first year for DPF
LML- same overall package externally but got internal revisions, CP4 fuel pump is crap.

Destroked is the one who makes a harness, and uses the pcs xfc box to allow the allison 03-05 tcm work in most anything. They will be of NO help what so ever in swapping a duramax/allison combo into anything. I called them and they told me that I had to make my allison stand alone to work as a swap even though it's behind a duramax.
