Ford 7.3 vs 6.0

[Jeepin']

I know the difference is liters, but what makes the engine that much better?  Everyone says the 6.0 engine sucks, so I want to know why?  Im not big into diesels so take it easy on me.

[Alba450]

The 6.0 is faster because it has more horsepower and tourqe

From my knowledge, I think the 6.0's have bad  injectors

If you want to buy one, just wait for the 08' twin turbo 6.4L

Is that sarcasm I sense?   Ive talked to alot of people who will not touch the 6.0.  If they are so bad and customers hate them, why does Ford even continue to keep them in their trucks?  No way can I afford a brand new truck But if I could, the new F450 would be mine

 The 7.3 has been around for a long time. IHC and Ford have been getting a little more power out of it every year till about 2003. They cannot get the design to meet current EPA regulation.
 The 6.0 in IHC trim (only about 270hp) is pretty reliable. Ford hopped the power curve up to make it more appealing for pick-ups. Ford rushed to get this unit in the F series and acceptable to EPA regulations. There was not a lot of real world R&D before the 6.0 hit the road. The first units had many gremlins. The last two years they seem to be holding up well.

Me, if I could find a low mile 7.3 I would by it. If you get the 6.0, get a new one.

I'm guessing Ford stuck w/ the crappy 6.0 b/c it kept the trucks heading back to the shop for work.  Giving the company more money.  The 7.3 is too efficient and didn't have any problems.  As for why exactly the 7.3 is better I don't know but I won't touch a 6.0 Ford.

Ask Mudfreak, Chillin, or Anoriginal.  Forgot some of the others on here that are real Ford owners.

Oh so the big uproar is the 6.0 is more problem prone?

I have a early build 2003 6.0(the worst of the worst) and I couldn't be any happier with it. The truck has 68k miles, tows a 12,500pound trailer, goes 95mph on the interstate with 17mpg, and has never had any trips to the dealer for anything other than 1 sensor change. Also, when you are comparing these engines, don't forget about the 2nd most important part of the drivetrain, the transmission. The 7.3 is very reliable, but has less power and a transmission famous for blowing. The 6.0 is famous for blowing but has more power and a rock solid transmission. Where you run into problems on the 6.0 is not injectors, it's putting chips and blowing the head gasket because the head studs are too elastic. You can upgrade the head studs and not have much trouble out of the engine. Of course the easiest way to do the studs is removing the truck cab.  I also FIRMLY believe the reason my truck runs so good is because I don't baby it. I run that truck hard. However, I always change the oil every 3-5k miles and fuel filters every 15k miles or sooner. If you baby the engine around and don't give it a work out I think you will be more prone to problems. If you go for extended periods of time without filter replacements your askin for trouble.

low miles? what? its a diesel. arent they made to go like 500,000+ miles? i thought that was one of the 2 points. torque and long lasting. well, them again, were talkin bout ford so maybe low miles is better.

What?  What's that I hear?  Hmmm sounds like a homeschool tormenting coming in for landing.

HEY Homeschool.....  Yes the 7.3ltr is good for 500k miles, but the rest of the truck isn't.  Remember you have to look at The WHOLE truck.

BTW I have 160k miles on my truck and only had to replace 1 water pump, 1 starter and 2 injectors, and thats just in the last 20k miles.  I'm still on the orginal clutch.

Ask any ford diesel mechanic. they have all seen 6.0s with 350-400k miles on them. they will last a long time but like freak said, the rest of the truck might not. and that is any truck, not just ford. 500k miles is a lot of wear and tear.

[Fox17]

true. i guess i forgot we were talkin about a ford truck here. im so used to my toyota. never had anything but tires and wiper blades replaced. 108k miles and runs like it just rolled off the showroom floor.

yea, toyota does have the quality issues under control.

[cutngrs]

i have 03 6.0 over 150,000 miles on  and love it   and lets not for get  i have alot of mods on too and pull a lot of waight  also but i have seen the new 08  and they hull azz

your both right.

But FOX can your Toyota haul a 15k lb trailer and a full load in the bed doing 70MPH down the highway???  I doubt it.  

[kuma]

I have a 2006 f350 4x4 6.0 and love it its a very thirsty beast but the add ons I have really don't help. Knock on wood nothing wrong yet.
If you want to wait Toyota is talking to CAT now about a possible joint venture for the new Tundra in 09  ...........But as far as reliabilty depends on how you treat it.

no, but i dont need to. the new one will pull 10k lbs. my point was not for you all to get toyotas, but to basically say fords have quality issues. all that about my truck and toyota had nothing to do with this thread but i just put it there. i really dont know why. lol.

I am wanting an '08 so bad, but the one I want stickers out around $58k. Gonna keep my current truck until its payed off and then trade in on the new body style. I don't believe in trading in vehicles unless it is for your dream vehicle. Unfortunately I have done that for my last 3 cars so my wants keep getting bigger and bigger and now the only truck I want is $58K, I know after that I can only go to a CXT or F650.

[MuddFreak77]

Hey Cody,  The new 6.4 requires a Cab off repair on EVERYTHING except an oil and Fuel filter change.

Thay can keep it, I will stuff a Cummins 6.7ltr in my ford if and when it blows up.

[Chuck_Norris]

I know the difference is liters, but what makes the engine that much better?  Everyone says the 6.0 engine sucks, so I want to know why?  Im not big into diesels so take it easy on me.

So you want to know the difference between the 2 Here it is in a nut shell. The 7.3 does not have an EGR system on it. This would not/does not appease the tree huggers. Now the problem prone  6.0 has issue with the EGR system, Head gaskets and turbo's that are sooting up due lack of exhaust flow and exhaust recycling. The issue would be better if FORD did the proper R&D prior to introducing the engine to the fleet. Kinda like the Harley V-Rod and the amount of time invested in that engine development. Sure I realize that anything mechanical is going to fail, it is just a matter of when . But in a manufacturing time when seeing how thin you can make something and how much you can make from that is the mentality, you can  not expect reliability. Ford motor company wants to shift the blame to the public, stating the add on's and modifications contributed to the demise of the power plant. OK well if that is simply the case then, why are they suing Navistar. Ford lost 20 Billion Dollars this last year not all comprised of the 6.0 liter but several ill-fated choices made by the higher up's. to rob great phrase" the fish rots from the head down". when you have a surge pushing a boycott  http://boycottford.com/  you can certainly feel the influx of the public when they respond. Hello your not doing something right FORD and the rest of your employees suffer as a result( sorry just venting) 
 Man this has to make you feel good. IT is hard to support something you enjoy when the parents wont embrace their family (employees) or their kin (public sales) It will be interesting to see how low FORD will go before it turns around. 

[digginfool]

I'm Ford through and through but it is discouraging.  I own 14 F series with the 7.3 and 2 with the 6.0.  A couple of the 7.3's are pushing 300,000 miles and still going strong.  The only problems I've had are in high use body components (specifically door arm rest bracket cracking) but that is probably a function of the door being opened and closed 30 times a day and employees that don't give a crap.  No problem with the 6.0s yet but they are still low miles.  We also have two 7.3's that are highly modified - big turbo and injectors - and they are very reliable as well, not to mention very powerful.

The real chuck norris just stood up.  Chuck you bring the facts.  Great explanation.  I will stick with my old slow reliable 7.3 powerstroke.

[Fox17]

that is sad. the arm rest falls off and the entry assist handle repair? what the heck? i used to love them but this is why i hate em now. if they dont get their act together, they are goin under. maybe movin to mexico will help. lol. yea right. o well.
