Best Powerstroke for WVO?

So what is the best motor for a WVO conversion?

6.7 -- brand new -- any data?
6.4
7.3

We wont even talk about the 6.0

Time for a new truck and if I cant find one already converted, I will convert it.

No brainer.
7.3

Specifically a 1999, 2000, or early 2001. They have forged rods.

Excuse my ignorance - but whats the forged rods have to do with the WVO conversion? 2002/2003 do not?

Finding a lower mileage (100k or less) 7.3 has been challenging..

any 7.3 will do fine. but for a 99-03 would be easiest to convert. they already have an electric fuel setup so its nearly half done compared to an OBS. the 94.5-97 (OBS) has a mechanical pump that needs to come out and be converted to electric.

youll be hard pressed to locate a 100k or less mile 7.3/ IMHO, find one that has good maintenance records, and good compression, which shoudlnt be hard. id look for a 200k or less if it were me. mileage doesnt bother me with a 7.3, as long as the air has been kept clean, and oil changes were on schedule as well as other maintenace it should be fine. im about to turn 300k and it runs like a champ.

The 7.3 are definately fine engines. The 6.0s are not much different when it comes to the fuel system - still a dead headed fuel rail setup which makes it great for WVO. I curently have both a 6.0 vegistroke as well as a newely converted 6.4 vegistroke. I am beta testing the 6.4 and there will be some changes to the conversion comming soon. My 6.0 has 150k trouble free miles - 105k of those miles running on vegi. I say trouble free, what i mean is no problems other than those cause by me.

The forged rods allow for room tho grow See signature.


I disagree with Clay on the suitability of the 6.0 for use with VO.
I chose to not deal with the turbo, injector, egr and head studd issues involved with the 6.0

We searched for months to find a 112K mile Excursion limited with a 7.3. Flew to the east coast and drove 1500 miles home just to get a 7.3.

The 6.0 trucks are plentiful and inexpensive for a reason. I would sooner work to upgrade the D2 system of an OBS truck before I did a 6.0.

Just my humble opinion, I could be wrong.

What does any of this have to to with WVO compatibility? Albeit these are ligit concerns, i have not suffered any ill effects from said issues...yet.
My tuner disables the EGR valve, this in turn eliminated the issues related, ie; egr cooler, head gaskets, etc. The turboes are really only a problem when they are babied. The injectors suck azz i do agree.

You in fact are CORRECT. It does not really affect WVO operation. However, it does effect the overall cost of ownership is why I pointed these points out.

So no one has talked about the 6.4. What is different with the engine that it does not support WVO as well? I can tell it's more of an issue as finding kits or people who do conversions on 6.4's seems challenging.

On the 6.7 its set for B20 is my understanding - anyone know what it would take to go to all WVO?

Or is the biggest issue that it would void the warranty? Very valid concern until you get to 100k miles.

I have found 7.3's under 90k miles in the $20-25k range. I have to say I like the 2008 - current body style better - but this is not all about vanity. I will want to start running on Bio, WVO, Palm Oil (possibilities of some time south of the border where it is plentiful)
