The Tbird in my sig has a 4000 stall converter and 4.30 gears in the rear.
It gets just over 20 mpg on the highway with the A/C on. That's exactly what it got when stone stock. Tuning, proper engine building, and attention to detail make this possible.
Like IBAdrian stated above-this are FAR different now than they were 35 years ago. It would not be possible to run a 4000 stall coverter in any street car-you'll smoke the trans or be getting 3-4 mpg driving it around above the stall speed.

If inwas a betting man I would too. I went into a walmart the other night and it was getting remolded. The company had 5 SD work trucks 1 250 the rest 350/450s. I noticed a 05ish 350 I walked and asked and he said it was an 05. It had 372k miles. Only has had 1 turbo put on. If the story is true thats nuts.

 

How fast where you going?

 

I wouldn't that not being able to run 5k rpm is a shortcoming for the PSD, it just simply doesn't need to.....

Yea, mainly because they weigh maybe half what you do....

You really like to bash the 6.0L don't you; People like you are the biggest reason the 6.0Ls have the reputation they do. I'll be the first to say they had their issues, especially early on, but the way you say it, you couldn't get a mile down the street before you break down.

How much real world experience have you had with the 6.0L?

 

mine has been in the shop 3 times in 200k. first time was for a couple injectors (that was when i was using wix filters). second was for hpop (the reason it went out was because first mech didn't tighten oil rail and hpop was leaking for 2 wks) and the last time i carried it in before i left on vacation in feb. to just ck it out while i was gone. they found my egr cooler leaking and replaced it. now all was covered by my esp so total out of pocket was 250. got my esp included with truck because they wanted to move it before the 08 models came out.

 

You know it has'nt had much. Between the back of a low boy, the shop, and the side of the road there just aint much more time left for him.

 

Yes, for the last time. I was one of the luck few 500 or so that got a buyback in late 04. My experience with the 6.0 was riddled with 2 engine replacements and finally a lemon law return in the end. My truck had just about every problem there was. Both times the engine was replaced while in my hands was hydrolock once for a head gasket problem, the other for a head problem. The turbo was replaced once and the truck was constantly over fueling. I returned the truck to the dealer a third and last time with a hydrolocked engine and 36,700 miles on it. I relied on this vehicle to get me all over the u.s. At the time. I was on a travelling mod team for lockheed modding uh-60 helicopters for Search and rescue. I was late for contract work twice because of this truck, nearly costing me my job. I'd rather have the reliability
Of my v10 for work like this. All it Has to do is get me, my tools and my rv where I needed to go. The v10 does that without ever presenting a problem.

To be honest, it seemed like id get about 1000 miles on a fresh oil change from the dealer and something would happen. The side of my camper was covered in soot and the truck was just a pile of garbage. Never again will I buy ford diesel. $45,000 and couldn't make it to 40k. I was luck enough to be able to re-purchase my previous truck for a reduced price back then. Hell, I only had the 6.0 for 5 months. I'm going on 12 years with the v10 now ( minus the 6 month span of diesel ownership).

 

I guess I've been spoiled with the 7.3 that is in our 2000 Super Duty... that thing has towed big trailers long distance, rescued family members from the towing companies towing even other full size trucks/SUVs like they weren't even there, moved me like 6 times (loaded moving trailer plus bed stacked full of stuff 2-3 ft over the cab with tiedowns) and all sorts of other craziness without any complaints or real issues.

Its only been in the shop 4 times total in 11 years and given us 1 major problem not related to the motor at all. "Major" problem was the brakes locking up due to the slide pin issue which we fixed in the driveway with the updated pins. The other issues were replacing 4 glow plugs and troubleshooting a faulty wire in the 4WD system that took the techs a few repeat visits to find.

Towing the same trailer with my father in law's V10... just seems like the thing is working harder, is not as smooth and you really have to romp on it sometimes. Yeah it moves it fine and does the job well... just a characteristic of the gas motor but still feels like the 7.3 will pull a house without even trying. Cannot say the same about the V10... I know I know, it will still do the job but my personal preference from driving both is the diesel and I would not want a Super Duty without one.

Yeah I can't see any part of the boat or trailer behind the TT while traveling. Only time I get to see if the boat is still back there is when I make a corner. lol

I am looking to get a dvd/navi unit this summer for the X so I can have a back up camera on the back of the X to see the hitch while backing up. Then someone mentioned having a camera on the back of the TT so you can see backing into camping spots and see if any living things are behind the trailer while backing up, I figured that would be nice for checking in on the boat while traveling as well.

I was white knuckled the first time I towed the whole deal but was relieved everything went smooth and the trailers handled better then I thought they would. When making a corner the boat trailer would track only about a foot into the corner more then the TT. It is a conversation starter as well I found out the first time pulling into the campground. As I was driving up to the camp sight about 15 people started yelling for me to stop and scared the crap out of me. Guy came up and asked "what do you do to tow two trailers?"

Before I would have to use my beautiful 96 F250 with a 351 to tow the TT up to the camping sight, come back home to get the boat and family and go back. Pulling the TT the truck got at best 9-10mpg while struggling to keep 70mph. Towing the boat about 12mpg. Now I can pull both and haul the family and all the gear all in one trip while getting 14.5mpg and holding 70mph without a problem.

Only issue with the whole deal is getting pushed around a bit when getting passed or passing a semi truck or big box truck. That may have a little to due with my tires being at 70psi instead of all the way up to 80psi.

 

I am truly sorry for your bad experience. But, your issues had more to do with a unlucky build on that particular truck than it "being a 6.0L", you simply have had a lot better luck with your V10. I'm glad you like it and it has served you well. But it is not at all a good comparison for everyone else, there are way more reliable 6.0L out there than v10s, total numbers wise, not percentage wise. Your issue was a very rare occurance, and most 6.0L owners never see anything like that.

I also have a little suspicion that part (or maybe most) of the problem with your truck was technical incompetence by whoever was working on it..... I can see the problems with the first engine, but second time around.... I have to chalk that up to incompetence on the techs part....

 

More like it can't. The super heavy engine components will not handle the centrifugal forces.
Our (same age as 7.3l) Mercedes diesel redlines at 5300 rpm and I run it at 5000 rpm on occasions. Than the old clunker makes 0 to 60 in less than 9 seconds.

 

I'm suspicious myself. In 03 and 04 techs didn't know how to work on these engines. They threw parts at them. Had to be an aggravating time to say the least. The 2nd engine failing? Blowing 3 sets of head gaskets stock no doubt withing 5 months. But the list doesn't stop here. This story really doesn't matter we all know the 6.0l had its problems and they got fixed and there's fixes for the ones that go down later in life.

 

And a gas engine will not handle the boost that these diesels make.

The gas is designed to make power up high, the diesel is meant to make it down low.

That is why a diesel pulls "nicer".

 

No it more like what's the point. For putting tq down the psd has the right range. The higher rpms doesn't mean anything else. Give yall alittle more speed maybe. Speed limits are 70 mph so this arguement is redundant. The 6.0 has a 4200 rpm redline. I've posted video of me doing 4200 and over. I'm not going to intertain the thought of it holding those rpms for any length of time. For the most part cause there is no gain to be pulling over 3600 or so. My trucks speedometer only goes to 100. April 27 2011 I held my truck right there for 75 miles and I was no where near 3600 rpm. I have no disadvantage of not turning 5k. At the same nobody has been able to offer the disavantage other than "my truck can"

 

The gas and diesel can both do the job.

The gas does it with higher RPM's

The diesel does it with heavier parts and a turbo charger.

Diesel use less fuel, but if gas keeps getting relatively cheaper, it's becoming personal preference more than anything else.
