6.0 hands down. You should be able to get it considerably cheaper than the others and it just had the common issues fixed. Throw a coolant filter on it, some rev-x in the oil and enjoy the better mileage and cheaper cost of the truck. Don't forget cheaper insurance and tags as well. For a business it makes perfect sense. I have one too for all the above reasons, cheap powerful truck that isn't half as scary as the internet makes them out to be when you leave them stock.

I'm not trying to start anything, but the 6.0's are pretty bad. (In stock form) My dad does fleetwork and we constantly see 6.0's with blown headgaskets, EGR coolers, and much more. just a lot of things. I know most can be fixed modified (Head Studs, EGR delete, Tuning) But stock it's just not a good idea. I'm just saying that we work on several fleets and see A LOT of 6.0's....I'm not trying to be cocky just giving my .02.

Do those two things on a stock truck that doesn't already have a plugged oil cooler, chip, or history of problems and you are good to go. Sure there is some risk, but the cheaper up front cost and operating costs more than make up for it in my book.
If they were as bad as you read on the internet, why are they still on the road? All the people I know first hand that have a 6.0 that is 100% stock have had very few problems. Clean oil and clean coolant is super important.

There is alot of risk with a 6.0. They are cheaper up front cause no one wants them. They have the same operating costs of any other 3/4 ton diesel. He never said anything about reading stuff on the internet. He said his dad works on them alot. They are still on the road because no one has towed them home yet. Just my rant. Dont want an arguement
However, bombed, the 6.0 is a bat-outa-hell. Even more so when compared to a 7.3.

Before I start my rant, dont think Im knocking the Allison. Its a dang good tranny, but I think the Torqshift is better. I personally have never heard of either a Torqshift or Allison breaking at stock power levels, the difference is when you start adding power. The Allison in stock form doesnt like tunes over 70-90hp, they start slipping and can go into limp mode. I know numerous individuals with 6.4 PowerStrokes running Spartan 210 or 250 tunes (210hp and 250hp over stock, respectively) everyday with no problems. And they can hold the 310 tune for 1/4 mile runs and messing around, but theres no way I would run it everyday.

The Allison is not a racing transmission. It was designed for pulling. Torque shift was designed to run the motor at red line from all I can tell, I hate it.

For arguments sake... 6.0's have issues but there are plenty of stock 6.0's on the road with no problems... Fleet trucks get abused by drivers period... Don't matter what it is. Tuning a 6.0 without taking care of the issues that are well known is an accident waiting to happen. Early model 6.0's had more problems then later year's... I would not hesitate on a 05+ 6.0...

i think since we are having this discussion about the 6.0 and not the other two kinda proves the point in a way. I like when we get to the same conclussion on different paths 
good luck with which ever truck u pick. Remember these are just our opinions. Its your money. So make sure you get the truck that you feel suits you. Good luck and no matter what we are to help with whichever truck with whatever problems. Happy towing

I have been thinking about putting a cummins in my 05 F-350 It is a 6.0 with torque shift. I was planning on keeping the torque shift, but I was told it wont hold up. The low end torque will kill it. They recomend a 48RE, Allison , or putting a manual transmission in it.
