Engine swap

I have a 04 f-250 4x4 with the 5.4 auto. I am thinking about swapping to the 6.2 boss when the engine goes later. Anybody have any idears on what all needs to be changed.

Everything. Transmissions, PCM, wiring harness, it would be a HUGE swap

By the time you spend all the money and your time on it just buy a newer truck with the 6.2. It will cause far less headaches

Why not a V10 swap? That's within the realm of possibility. For the most part it'd be a plug and play swap.

Haven't really thought about. It runs good, it has 240,000 on it. And I pull a 36 ft fifth wheel with it.

If the time came I'd suggest adding two cylinders and call it DONE. You'd have ~25% increase in horsepower and torque for a factory-engineered plug and play setup. That has my vote.

So the V- 10 is plug and play with a 5.4 truck? What about the tranny and exhaust y pipe?

The 4R100 they stick behind the 5.4L is slightly different internally, and therefore the ideal solution would be to get a donor engine and tranny. But the V10 will bolt up to your tranny, but it might not last as long. Also the PCM and main engine harness would have to come from the donor truck. I don't think the exhaust is different though, but I'm having a tough time confirming that.

Ok thanks for the info. When the time comes I'll look into it further, for now I guess I'll just change gear ratio.

Too bad they don't make stuff like the sbc. Part interchange ability would be a nice thing. What has me wondering is if you would be able get the fuel injection to bolt up and then swap over sensors and worry about tuning. Or is the ignition system also to different?
