6.0 vs 7.3

So I am looking at purchasing a superduty crewcab shortbed, with a diesel motor. But I am a little confused on the difference between the 7.3L and the 6.0L My Dad has a 7.3 in his 96' and I have always heard goods and bads about the 7.3, but I was looking the other day at two (what I thought were identical) trucks and noticed different motors! Is the 6.0 a replacement for the 7.3? And is it a better motor? Should I be looking for a 6.0 or 7.3 I guess is my question.

Thanks

I am going to keep my 2002 until Ford works all the minor kinks out of the 6.0. I hear mixed "luck of the draw" on the 6.0 trucks. Some have really reliable ones and some have one with a few problems.

Yes the 6.0 is the replacement for the 7.3. It has some bugs to be worked out.

I agree with Michael013. I was in the same boat late last year (7.3 vs 6.0). I took the 7.3. History shows that every manufacturer has trouble with new designs, and I didn't want to be a guinea pig. I also know that I am a gearhead, and I would be hot-rodding my diesel. When I was truck shopping, the choice of aftermarket mods for the 6.0 was limited and very pricey, and still is higher than mods for the 7.3. I never did test drive the 6.0, but 2 months ago I got to drive a 6-speed 6.0 (bone stock) on a 100 mile trip. The only thing that impressed me was the new turbo. It spools up very quick. The engine's "sweet spot" was very narrow. Had to upshift too early. Overall, I wasn't very impressed with it, but like I said, it was stock with a manual trans. If this engine was modded a little and mated with the Torqshift, it may be awesome.

ya that new 6.0 and torqshift are unstoppable!!!! the voluteer fire department got an f250 long bed crew cab with one in it, and since i knew the guy, we had a little drag race from a dead stop, and even with me having the hypertech programmer, he whooped the heck outta me!!! I'd go with it personally, but its all your preference, just remember, they have a 100,000 mile warranty available for a reason, to keep you satisfied!

I had the Hypertech programmer, and I used them for years. I also paid $449 each year for them. I purchased a Superchips MT 1705 last month for under $300 from motorhave.com. I run the medium setting 90 HP. If your 2002 is automatic, that will give you about the same performance if not more. There is a 110 HP setting on the SCMT 1705.

I did order a E350 extended van with a 6.0 through Ford Fleet, to try it out. Delivery is 6 weeks, more or less, probably more. I'll let you know how the 6.0 runs in the van.

6.0 vs 7.3

I hate "first engine bugs". So I'd stick with the 7.3 cause its been proven over and over (254,455 miles on mine and still running great). Also if you want longevity the 7.3 at this point makes more sense. The more power you squeeze out of an engine the shorter the life span. 1.3 extra liters of displacement is a good thing. Look at the diesels in a semi. They have BIG engines but aren't producing HP ratings like a pick up. The displacement to HP ratings & torque ratings are less in a semi than a pick up. Semi engines also last a lot longer. I have a stock 94 7.3 PSD. 225 hp with 450 torque. It pulls a fully enclosed trailer loaded with ease. Yes I do get passed by newer more powerful diesels but I want it to last. Who cares if I get there 10 minutes later. Just means the BBQ is already warmed up.

I thought those Semi engines were in the 400 - 600 hp range? I know the EMD-710/16 makes 3,000hp @ 900 rpms....but that is a train engine too....and a 2-stroke.

Yes semi engines make that much power but look at the 6.0. 325 ponies with 363 cubes. For example the Cat C-15 is a 14.6L engine with 882 cubes. It makes from about 425-525hp and about 1500lbs of torque. On the 6.0L PSD each cube makes about .9hp. On the Cat 14.6L each cube makes about .53hp if you take the middle HP engine option. So the 6.0L makes almost twice as much HP for each cube. But in the world of semis torque is the subject.

One more note, the C-10 makes about 320hp and is a 10.5L engine if I remember correctly. Same HP almost twice the displacement.

As for the train engines, all they turn is a generator to power the electric motor driven trucks on the locomotive.

The warranty doesn't do you any good when the truck won't run and Ford finally tells you they have no clue why....

Had a friend get one (because 2002 went through 3 trannies so Ford gave him a new 6.0) Too make a long story short the thing craps out on him 3 times, each time back to the shop ... till they finally tell him they have no idea what the problem is or how to fix it... of course they won't provide him with a loaner etc through all this.... way to go Ford, that guy will never own another Ford.

It may be the luck of the draw and that a good one runs great but from what I have seen if ya get a bad one your SOL and you may even get their 'U #2' service too boot

HP is really irrelevant since you are comparing engines governed at different rpm. Remember that HP is a calculated number that is derived from torque. The higher the engine's rpm, the higher the HP/ci will be. That's why the same 6.0 engine that Ford is putting in the F250-350 rated at 325HP@3300RPM/560 lb/ft @2000RPM is rated for much lower HP in the medium duty trucks and the International version, the VT365.
