Once you fix the clamping issue on the top end(head studs) and remove the problematic EGR, the bottom end of the 6.0L is proven to handle more power than both of these engines.

The 6.0L has several problems that cannot be solved with “bulletproofing” such as not enough head bolts per cylinder which can result in failed head gaskets even when studded, a POS bedplate that is prone to leaking oil that requires pulling the engine to repair, and “snowflake” injectors that seem to fail when someone walks by the truck with an ice cream cone. There are several more issues that I won’t bore everyone with the details. I’ve been there owning one, have dealt with many others at my work that were all POS sooner or later and would not wish one on anybody (or almost anybody)! :B

Sorry but the 7.3L was and is light years ahead of the 6.0L.

I have to disagree based on my experiences and what I have seen. Seen many bulletproofed 6.0L at NHRDA events and off the track with well over 300k on them handling more than 450 at the wheels all day every day. Also, don't tell Charlie Keeter this. He thrashed that 6.0L with so much nitrous to win back to back XDP Diesel Power Challenges.

It cracks me up when people say the older diesels are low power engines.
That’s easy to adjust, with the right turbos, a set of head studs, some injectors and other tweaks.
It’s the tuning that sets the power level.

The advantage to the earlier models is simplicity, which inherently means reliability. The less there is to go wrong... the less goes wrong. You just can’t get around that.
If you turn all your own wrenches, you don’t want a late model.

The newer ones are super quiet and come already set up to make better power, they’re easier for someone who just wants to buy something with a warranty and isn’t up for setting it up themselves.
Both are “better” in one way or another, it’s an apples-to-oranges pointless comparison.

That old 7.3 can make tons of power if you want it to, it’s got more displacement. But it won’t do it quietly.

The 6.7 is a better engine and a better total package.

I can't imagine a circumstance where I would be buying a 7.3 (or a 5.9 for that matter) in current times.

The fall is really not that far till circumstances change your perspective.

Great, more wasted beer, spit onto my keyboard! :)

My family owns a 2002 Super Duty 7.3PSD and for farm work its been hands down the best truck we've owned to date. Having said that, I probably drive it maybe once a year at best and when I do I just can't believe how archaic the truck and power is.

My personal truck a 2012 Super Duty 6.7PSD has been extremely reliable to date with 164k miles, and power delivery is far superior to the point there's no comparison.

As for tuned trucks I can't comment from personal experience but around the Houston area there's some really serious tuned 6.7PSD running around that can put some shame on some really fast cars.

The 6.7PSD has quietly received some really large connecting rods and will be getting steel pistons this year, and I look forward to see what kind of abuse these things can handle.

Bottom line I have a lot of respect for both engines. Long live the Power Stroke!

As great as the 7.3 was in its time, the time for a 210 hp Diesel engine in a full sized pickup has passed. All the reliability in the world couldn't convince me to buy such a rig these days unless I was severely budget limited.

Finish dressing it (studs) and get rid of the gluten (EGR) and a couple other little things and they're as solid as any of the engines out there.
And nothing sounds as cool as a straight piped 6.0 that is still wearing it's vgt!

Was it a problem. Undeniably yes, and it was/is more work than most care to who should not have to dump money on top of paying a premium price for a vehicle that could lift a head just driving to the store for some gluten free flower.

This would be a tough one. In stock form or with mild tuning, I would have to say the 6.7L. Modified I would have to say the a 99-00 7.3L. Most of what was added to the 6.7L like VGT, common rail, and so on was for emissions. A modified 7.3L can easily make a reliable 500 at the wheels with an S400 and a few other goodies.

If we are talking all modified PSD's then I would go with a bulletproofed 6.0L, but that is not one of the choices here.

I have to disagree with you on the 6.0. It has a terrible reputation and is not worthy of being in the same conversation as the 7.3 or 6.7.
In an ideal world Ford should wish it could just eliminate the 6.0 from its history and pretend it never happened.
But you are right the 6.0 is not one of the choices so maybe my comments are out of bounds.:(
