99 5.4l carb conversion?

Lots of threads on carb conversion for previous generations, none for this gen that I could find.

My 99 f250 light duty had been continuously plagued with electrical issues the last couple of years.

Overall the truck is in great shape otherwise. Used primarily as a farm truck, would love to just get rid of everything electronic and get a carbureted setup

i am guessing not easily possible since no one seems to be doing it.

What will you use for a distributor? How will you drive it?

Also, define:

electrical issues
That may be GEM related due to a leaky windshield-a definite 10th Gen truck rite of passage. Let’s not throw the baby out with the bathwater just yet.

Otherwise, buy a bullnose or bricknose. Turning on your headlights doesn’t go through a computer with those trucks if you are really serious here.

No idea how things on this work from what is in computer vs not. No idea on distributor, but think I have my answer based on questions

just to explore the idea a little bit, is there an easy engine swap from an older Ford that would bolt in nicely?

Needs to be fairly easy, new at this type of project

There is no older engine that will be an easy swap. If you're good with a lot of fabrication there are engines that would work.

Just sell the truck

If you cannot handle wiring and cannot fab, this project is far beyond your scope.

Conversion possibility

I've been researching this topic, since my truck had electrical problems. It's possible, but it requires some investment. Mainly a modified intake for the carburetor, resistors for The injectors used to trick the PCM would be between 15 and 25 ohms and have a capacity of about 50 watts; the fuel rail is eliminated. A regulator is installed to lower the pump pressure from 55 to 6 psi full for use with the carburetor, thus preserving the PCM's ability to manage spark and transmission without causing problems. According to my research, the carburetor to use would be a Holley 600cc, as the engine requires some fuel flow. I'm not guaranteeing that all of this is correct, but it's what I've been able to find out.


Note: If anyone manages to do this, please share the information; I'd like to try it sometime.
