v10 to v8 engine swap

I am new to ford ownership (hopefully soon) and have a opportunity to buy a 99 F350 SD with a V10. the engine is shot and I was wondering if I might be able to put in a V8. I will not be using it to do the work of a V10 so I don't think a larger V8 will be underpowered. It has an automatic 4x4 transmission. It will mainly be used to haul firewood and maybe tow a 22' boat that a 5.7 L GMC or a 5.2 L Dodge handles fine. Is this feasible? I am guessing I will need the correct computer for the V8 but anything else? will the trans bolt up ok? new motor mounts? I can do an engine swap on the 95 GMC suburban with no problems, am I getting in over my head on a Ford engine swap V10 to V8? thanks deputyb Central IN.

Seems to me that with all the wiring harness and PCM changes you'd have to perform that it would be easier just to replace the V-10.

Replacing the existing V10 would be the easiest. You should be able to find a fairly low mile 2V NPI or PI V10 at a salvage yard for fairly cheap, check craigslist also. The 2V V10 is still being produced to this day for the E-series vans so a wrecked late model E-series is another place to pick up and engine. The next easiest swap to make would be to put in a 5.4l V8.(Basically a 6.8l with 2 less cylinders) You would need the complete wiring harness and ecm for the 5.4l to make things go easier.

Swap it out for another V-10. You will appreciate the V-10 a lot more than the 5.4.

Yeah from what the 5.4 owners are claiming with fuel mileage, it would be easier to swap the V10. If you've already got the V8 it still wouldnt be worth it.
