The only 5.9 getting dropped in my frame rails is a DT360... makes the cummins look like a kids toy.

 

Hey true to the roots of navistar. Those were some tough but heavy power plants. Mechanical injection would be your choice I hope

Really I like the 6.0 PSD. My dad had one and sold it with 210k miles. It worked hard too pulling skidsteers everyday and traveling across Texas once or twice a week. The 5R110 trannys are awesome! I'd pit it up against an Allison any day to tell you the truth and I'm a GM guy. If you get a 6.0 then get all the deletes and head studs. You should be good. Also the newer the better. 03 will probably have the most lemons. Emissions were its downfall. The engines had to run hotter to burn cleaner causing blown head gaskets.

There's a guy local to me with one in his CC/LB dually F350 something like a 2001ish. Pretty slick setup. Carson Stauffer now has all of the adpater plates and such to bolt it up too. He did a really good write up on PSN about it.

Hypermax says the stock headgaskets/bolts are good to 300psi and the bottom end could hold 3000+hp.

 

If i were to build a 6.4 08-10 body and frame, scrap the engine and exhaust and radiator.

Throw in a detroit. if need be id chop the cowl off since they overhang too much as it is, and cut the fire wall out and re form it to fit an 8V92

 

Very well put, if you can wrench yourself its costs far less to bulletproof a 6.0L than to put a built tranny in a cummins or buy an airdog and a built tranny for a duramax and after that you have a truck that is heavier and nicer that will still compete with all the others

 

Y .02 have two 7.3s and keeping maintnence up bypassed the 6.0 and 6.4 if you have the time to work on them then fine have at it and fix everything that the factory that is wrong but the way it should be is you buy a truck and not have to fix problems to get it back to square one

7.3...(skip 6.0-6.4)...saved for 6.7

That i believe for me at least is the best way too go

by the way great arguments from all sides guys!

 

7.3<6.0<6.4<6.7 no questions about it man. Not knocking any of them, but if they didn't improve, they wouldn't have sold as many trucks as they have.

Does the 6.0 have some reliability issues compared to a 7.3? Of course it does. The 6.0 also makes more power and has a lot more emissions equipment. Did you know the 6.0 is 95% cleaner running than the previous 7.3 stock for stock? That's pretty impressive. A stock 7.3 is hard to beat in the reliability department but I know plenty of 7.3 owners who carry spare ICP's in the glove box man. They all have their faults. At least with a 6.0 you know what you're getting up front and how to fix it right away.

As for making power... 6.4 is king.

 

The more research I do the more I like the 6.0. But if you don't work on your truck than a diesel is not for you. Unless its under warrantee. By the time I can afford a 6.7 they will be out of warrantee. so I hope there not bad to work on.

 

Wow! I think I learned more this morning than all week!
