Torque the plugs correctly and you'll never have a problem.

 

this is a debate that has gone on forever and really over-exaggerated in some places.. Both engines have their own merits.. and both can be pretty reliable.. and no you dont have to spend a crap load of $$ to make a 6.0 one either..

Biggest words of advise i can give the OP..

1. Do you home work on both... both platforms have their own issues.
2. Dont let the bad raps of either force you into doing non-necessary maintenance. some people will try to fix a problem that doesnt exist and may never exist by scaring you into removing or changing things that dont need done. So many have done this and ended up causing the problems they were trying to avoid by not understanding how the equipment worked on the engines.
3. if your really wanting one over the other or feel your needs may change in the future.. get the one you really want.. dont let us talk you out of getting something you really want.

both the trucks are built to do the same job and can handle the work just as well as each other.

 

There is a diesel mechanic in my home town who will tell you he built his business on the 6.0. I think once you do the preventative stuff like arp head studs, the 6.0 is sweet. Comparing the v10 and the 6.0 isn't fair for either. The both excel were the other faulters. Me personally, I don't like the 3v. You'll notice the 6.2 is a 2v. The 2v is more reliable in my opinion. If money isn't a big deal get a Diesel. Just understand that everything about them is more expensive. Except maybe fuel cost. My 6.8 gets 9.8 MPGS last time I checked and weighed 7200 or so with the flat bed and all of my tools. My buddies Diesel weighed 11000 and gets 15mpg

 

I never owned a v10, but my trucks work for a living, work hard,we dont cut no slack on weight or miles,i can say from what ive seen on the road,heard from drivers,watched towing on serious hills across the nation diesel works good if taken care of,no hot rod tunes ever installed,350k on this one and runs great,but if your not doing alot towing or tow light a gas burner might be better for you,cheaper to operate,cheaper to fix,cheaper to buy so decide your use and pick what works.

 

Mark, I'm sorry but in case you didn't know you need to Bulletproof your truck right now because those TTY bolts are sure to fail. In fact, I think by 350k miles they're required by internet law to have failed no less than twice already, so you probably have blown headgaskets and just don't know it. My cousin's best friend's uncle is a Ford Junior Master Tech and he told me you have to stud the 6.0 before the FICM overheats and leaks coolant into the exhaust. They're GREAT once you fix them all up though

 

 

lol,ill get right on that.

 

I've owned almost all of them at one point or another. From 4.9L/5.8L/7.3L PSD OBS to pre and post PI headed 6.8L/5.4L and my current 6.0L.

Some of my own notes about each:

1. 7.3L is a pooch in stock form. Mileage is good, Longevity is wonderful but the thing is lacking in the power department and is insanely loud. Even with tuning and supporting mods, the 7.3L can struggle to get to stock 6.0L power levels.
2. Pre-PI headed V10s are waaaay down on power. The "quarter" sized intake and exhaust ports keep any power from flowing though it. I did everything from headers, 3" exhaust and gearing to get a somewhat tow-able unit, just to be disappointed.
3. 3v 5.4L feels by far more powerful than the early V10 and early 7.3L. Its a good "all around" truck. not the best and not the worst for everything.
4. 2005 6.0L.... Money pit. Can be unreliable at times. Fuel mileage is wonderful. Sounds INSANE with good exhaust. Mine is tuned, studded and modified and is faster than many performance cars. It's a "love/hate" relationship. You've got to be patient (and somewhat mechanically inclined) to own a 6.0L.
