7.3 Into a V-10

[Blueboy]

My cousin has a 99 F-250 that has the V-10 that he blew the motor in. He found a 2000 F-250 that has a 7.3 in it for $2,500. The truck that he is thinking about buying is pretty beat up and needs a transmission. I was wondering how difficult it would be to put the diesel into his gas truck and what all would be required.

Thanks for any advice

Some more knowledgeable folks might chime in but you are looking at a good bit of work I think. Fuel system, probably the whole engine bay almost, PCM.

There's a couple of people on here putting 7.3's in place of their V-10's into F-250's and Excursions.
But, if his truck has a good trans - I'd say use that since it should be the same 4R100 used in both trucks anyways, and just focus on the engine.
But Besides the tank, pump, wiriring harness PCM, IDM.
I'm sure there's a write up somewhere on here explaining it all.

The transmission will not stand up the the torque of the 7.3. It my be a 4R100 but a different animal internally. I would think it is more hassel than it is worth, you could buy a SD that is a runner for less $$ and head ache. Just my .02

Thanks for all the information. I knew it would be quite an undertaking, and that's before I thought about the fuel system.

I didn't realize the transmissions would be different internally. I thought they would be the same.
