1989 351w into a 78 f250. What fuel system to use? I'm looking for opinions. Should I try to swap all the EFI goodies from the 89 f250 to my 78? Would it be better to pony up for an intake, carb, and other little expenses to convert to carburetion? The Windsor engine is a runner, still in the doner truck, so I know every works as is. How much of a headache is it swapping all of the wiring, sensors, and computer to an old rig?

Yes sir, I'm swapping trannys too. NP435 for a ZF. What sort of incidental expenses should I expect if I try to keep the EFI? I'll have to buy a fuel pump either way, but I don't mind some extra work to avoid a $500 plus carb and intake setup.

On that truck the engine harness is pretty much stand alone except for the dash gauge wires and power supply and ground wires, you should be able to get most of what's needed out in a fairly tidy package. The '89 trucks also used a dual stage fuel pump setup with low pressure intank pumps and a high pressure rail pump. You have the whole donor vehicle so everything you need is right there, including the pumps if you swapped a gas tank, and an EFI motor would look pretty trick in a '78.

Thank you! That is exactly the kind of info I need! I was really hoping to keep the EFI. The truck runs and drives, but he said the clutch is frozen. I can have whatever I need off of it. I haven't seen the truck in person because it's an hour away. I'll be up there doing concrete before we start ripping and tearing on the rigs. I'll make it a point to take some pictures of the doner for study material. I just hope my 78 makes the trip. I really appreciate any little tidbits of advice or warnings you kind folks can provide.

Thanks for the link
I'm just realizing that the 89 has a serpentine belt system. Is this going to hose me? Will I be able to use the accesories off the 89 truck like the power steering pump and alt? How much of the emissions stuff can I leave off, and what to do about the gauges? I was hoping to be able to modify or fabricate most everything. I don't have any money to speak of in the "project truck" pot. I'll most likely have to buy a clutch and pressure plate already. I'm kind of counting on this being a low buck type of job. Not a hack job, but a clean "nothing fancy" type of install. I'm supossed to be PCSing soon, and may not be able to take the truck. If I'm looking at a sizable expense here, I might just have to unload the rig and cut my losses.

I'd make sure to keep all the serpentine accessories with the motor from the donor truck and swap them in as well. Should work okay, there might be a hose fitting different on the power steering pump (not too sure about that) but that would just mean having a hose made (if you can't find one that will work ready-made) probably to the tune of 30 bucks or so. Do either of the trucks have A/C?

Yes that'll work, the trucks were available without air so the belt will be an over the counter thing. An '89 without air would have the same brackets but the AC compressor would be missing.

Just a thought... If I leave my truck for more than a day or so, and it has rained, I sometimes find I cannot put the truck in gear after starting it in neutral. Clutch pedal fully depressed, it is impossible for me to engage any gear. Try reverse, and it acts as if the clutch pedal were at the top of its travel.
So, I have learned what to do when that happens. Put the truck in 4th gear, engine stopped, and then depress the clutch, and start the engine. The truck will lurch, or at least try, and as soon as the engine starts, the clutch give up its hold on the flywheel.
This has happened about 4-6 times in the past umpteen years, and it always has happened after rain and a short to long stay in one place.
Your potential donor may have a similar problem, given the rain the FL has gotten, no?

Check your firewall for cracks, rust, flex. Check your clutch pedal, brakets, rod etc. Defects here soak up motion in the system, leading to inadequate disengagement and contribute to sticking like you describe. If it shifts just fine otherwise, and no problems after you "break it lose", then it's unlikely you have this issue, but worth looking anyway to avoid future surprises.

85,
What's happening (I think) is that the clutch disk is sticking to the flywheel. I suppose it could be just the humidity... Other than the very intermittent sticking, and not enough to move the truck at all, the clutch works fine.
I live with it as is, but thought the 89 mentioned as having a frozen clutch may in fact be the same thing. Yah never know...

when i hooked up my power steering to my serp set up i took the hoses from both pumps in and got them made up. look for a hydrolic place they have the stuff to do it. just tape them together so they fit the way they should then the guy can cut them where he wants.
mine cost $50 to get made.

I'll have to try out that clutch thing. I was figuring on breaking it all apart, and inspecting it before I swap everything over. I should really know what's going on after it's apart. Thank you guys for all of the pointers.
