I just got rid of my diesel and went to a gas truck (6.8 liter). It will pull anything that I need, including horses. It is a simpler truck to own, and maintenance is less. I have absolutely no regrets getting rid of the diesel.

 

Awesome guys, thanks so much for the advice. Gas it is!

 

I am going to throw a wrench in here and suggest getting the '08-'10 with a V10. I have had both, the V10 and the 6.2 and would prefer the torque of the V10. The 6.2 just screams too much for me.

 

I would have to agree. I have driven both pulling 16-18(depends on who is loading) round bales with a 25000lb gooseneck trailer on the same hilly route, many times. Both engines pull the loads well, but the 6.2 does it at a higher rpm than the 3V 6.8. Both are great engines, I just wonder how long(mileage/longevity) the 6.2 would last working at those rpm's. The 6.8 revs are usually about 1000-1500 less pulling the load than the 6.2.


I would take either, but would prefer the 6.8. It gets the load moving quicker and seems to do it easier. Just my 2 cents.

 

Not going to take away from the V10, but the 6.2L was designed for high RPMs from the start. I see no reason to believe it can't achieve very high mileage. What would fail from running at higher RPMs? It has roller rockers, piston cooler oil jets, low compression, reasonably large oil sump capacity, iron block, etc. The Modular engines (V10 included) were always designed for making torque at lower RPM, but at the expense of top-end horsepower (typical long-stroke engine).

 

Basic physics. The more rpm's turned creates torsional rotating forces that produce vibration and heat that has been proven to wear our moving parts. I agree that it was designed for high rpm. Just curious about wear relating to mileage.

 

I just replaced my 2008 v10 with a 15' Diesel. The V10 was a great motor, towed well didn't have a single problem with it in 81,000 miles. However, the 15 diesel blows the doors off it. Very impressed with Ford's latest technology.

With that said, the 6.4 is known for having lots of problems, I would go for the 6.2 gasser in a heartbeat given the choices you posted.

 

Never owning a v10 . Do like my 6.2 got rid of a 7.3 for it. Was definitely the way to go. Id like to try a v10 also. But new it was. And you cant put a price on that with someones junk with a lot of miles

 

6.4 with a dog delete/egr delete you're good to go!!!
