5.4 to v10 swap
 

Just swapped out a 2000 5.4 superduty f250 engine for a 2002 6.8 v10.Everything was pretty straight forward except for the belt pulleys.The belt from my 5.4 is too wide for the v10.I ordered an a/c delete pulley for the v10 engine and it has 7 ribs like the 5.4.Is there different size crank dampers and power steering pulleys etc.?Can i swap out the wider 7 rib pulley from my 5.4 alternator and crank damper or not?
Thanks for any advice.

You should be able to swap them ok, look for a part number on them.
Is it the same or different?

If it is the same you are good to go.:-X22

Did that V10 come out of a van?

There are two widths, I think 6 rib, and 8 rib. My V10 has the wider belt, and it's a 2001.

The '99's, I believe, have the 6-rib belt, in the F-series.

I wonder if the vans didn't.

The engine came out of a 2002 f250.A friend who works on these told me it shouldnt matter.I just used the 6 rib belt and fired it up.Everything appears to be good and the truck has a ton more power!I ran into a couple different kinks like the fan clutch being different than a 5.4 so i had to buy one from a junkyard.I also needed an intake kit so i just bought a volant instead of a stocker.The other thing i noticed is the alternator is a 2 wire on the v10 so since i had the 5.4 alternator/battery harness i had to use the 5.4 alternator but it bolted right in so no problem.Maybe a year thing instead of a 5.4/v10 thing i dont know.
Thanks for all the help guys!

Something doesn't make sense. From what I remember, the early '99's in the F-series had the 6-rib belt, while 2000-up definitely had the 8-rib belt.

But, I think the E-series has the 6-rib. Weird. Very weird.

Can you email me, need to ask you some question about this swap. rubicon1272 at yahoo dot com.

I want to do this swap in my truck. How does the PCM work? Did you need the engine harness from v10 ?

I'm curious what all you did with the engine harness, body harness and PCM.

To make everything work, that is. Did you simply swap everything over from the donor truck?

V10

Find anything out. Pcm most likely needs swapped?

V10
 

Why volant intake. What about wiring harness and computer?
Thanks for all the help guys

Yes. Get a complete engine assembly. Much simpler that way. Computer, too.

This is isn’t like the old days with TBI setups where you swap a chip and a few other bits and the harness is the same.

How do you know that ? Same engine with 2 or pistons could send computer out for about 500$ get it programed and tuned

I got the engine some time ago I'm thinking it be best run crank triger and fabricated intake with two 500 carbs

The engine harness itself will be different between V8 and V10, and the PCM is most certain to be lacking the extra electronics to drive the two extra COPs and injectors.

Also consider a V8 fires 4 times per rev. A V10 fires 5 times per rev. Injector and coil timing for all coils and injectors is different. V10 COMPUTER or some very modified version of a V8 pcm will be needed.

V8 motors have weaker transmissions than v10s. Something about clutches and torque converter.
