I'm also interested in what it takes to make a 6.slow into a decent motor. Lot of them out there but nobody will touch them because of their problems.
You can buy a new complete engine from Ford for $15k and have a 3 year unlimited miles warranty on it. Complete engine. Not a long block...

A customer of mine in Granger is having an outfit do a complete Cummins 12 Valve swap into his 2002 F-350 for $12K with performance mods and a built tranny. An outfit in Hermiston is doing the work. I couldn't consider that kind of money into a 6.0.

Agreed, only reason I could think of is more power and better mileage but that's going to take many many miles to pay for itself.
Just now seeing this, I work on these daily. Not answering a bunch of pm's but I'll give some insight on here real quick.Don't toss the hpop, higher probability that it's a simple oil leak, or slow ipr.Bullet proof? Well, the phrase was coined by bullet proof diesel.Get arp studs, oem head gaskets, bullet proof egr cooler, updated egr valve AND 6.4 push rods. 6.4 push rods have a thicker wall and just slightly shorter, to keep rockers from stress.New updated stc fitting and might as well go into an updated stand pipe kit.Have the intake cold tanked or new intake manifold.Have temp sensor in intake cleaned or replaced, they're cheap.Bullet proof sells kits. They even use oem oil coolers, gaskets, o-rings etc.Want to get rid of ele controlled fan clutch? Buy the adapter so you can use mechanical 1997 fan clutch and alleviate that issue, ele has been know to shut mtr down when fan eats wire harness for lunch and wires cross and shortIf you're into it this far......thermostat and water pump. Split turbo and clean unison ring.Don't ditch the egr system. Keeps combust temps down, which keeps egt down.Remote oil cooler or oil filter is your candy. Baldwin and Wix confusion right now and many can't find right filter now. If you keep oil system stock, and take unit in to buckeys, Walt's, firestone etc, for services, just sell it. They use bad filters and cheap mis labeled bulk oil.Simple things such as an over charged or plugged a/c system will raise temps at condenser, which transfers heated air to radiator, same with a bad tc or slipping trans.Stick with stock ficm. Seeing lots of burned inj coils. Stock works just fine and seat of pants dyno won't feel any different, but wallet will.Watch aftermarket injectors........ many sell as new, but internals are cleaned and used. Oem are all new internals and coils, with warranty. The 6.0 sticks are so small, there's no room for error.

Isn't it true the only time the egr is active is during steady states (idle type conditions) and its closed during acceleration or loaded conditions there by eliminating it's operation in the very condition in which high egt's occur.
I understand it's modulated but it's main function is to reduce NOx, and yes combustion temps drop to accomplish NOx reduction but it's not used to reduce combustion temps for longevity, its only for emissions purposes. I've monitored several 6.0s for diagnosis reasons and have yet to witness the ecm commanding any egr percentage during a scenario where egt's are high. If what you say about egr removal were the case guys would be burning holes in pistons and blowing head gaskets left and right after deleting and you just don't hear of it. Do those things happen, yes but it's mostly from abuse,over fueling,or towing heavy with big tunes.

But, when you are pulling Blewett pass with 15k lbs on the back and even at 60% throttle to not fill the basement with parts, the egr is being modulated which helps lower egt temps, which allows for a more throttle.Yet, there is a limit. We have done hundreds of miles of exactly that kind of real life testing, with the engineer's that built the damn things running the lap top in pax seat.

There's allot of them out there.
Or just bring back the 7.3! Without the urea injection and all the other crap. You go Al Gore!You guys struggle to get 15-16 miles a gallon, with a 50k truck! The old Cummins got great mileage, the 7.3 gets great mileage . Both will pull a house over the pass! But lets fix that! Diesels put out way less Co2 than a gasser.Lets re invent that wheel. How many people do I know that have taken that new diesel in with fuel issues? A lot! One friend with a Isuzu / duramax . Couldn't figure it out.ended up putting a F.A.S.S system on it and getting rid of it.

Tell me the trick to getting "great mileage " with my 7.3 I'm all ears. Love my 7.3 wouldn't have anything else but 13.5mpg is not great by a long shot
2002 F350. Aftermarket cold air intake, 4" pass through exughst and 35/12.50 stt maxx's. It's got 160k on it and a brand new transmition. Had some sort of BS plug I chip when I bought it. Bout two weeks later the computer ew and I didn't put it back on.
