I didn't know that we were talking about LSx engines. Everything has been comparing 261's and 292's to 4BT's.
As far as longevity, I have seen commonrails (305 and 325 hp) over 500,000 miles. I would think that 200 HP on 4 cylinders would be similar to 300 HP on 6 cylinders.
Even if it only runs 300,000 miles, it will be a far cry better than the 7.3 that I took out - and still better than a stock 292.

I was just saying that because you said
"This winter when I have time I will hopefully get it over 300 HP and 700 ft. lbs of torque. Try that with a 292.", and I was noting that both are really probably the wrong choice if you're going for cheap power.
My understanding is that when running one really hard consistently (heavy towing/boat application) that they don't really like to make a lot of power, which is understandable.
I would be surprised if you couldn't make a 292 go 300,000, though. I think I had two people recently tell me that they had cars with 283's that they had for over 300,000, and a local 305 V8 went almost 500,000 before the timing chain fell off (IIRC). I'm pretty sure one of my own 250 powered trucks has way more than 300,000 on it, too.
Not to say the diesel wouldn't be nicer at 300K (I'm sure it probably would be), but you also have to factor in that the rebuilds cost more, plus the other stuff like injectors, injector pumps, etc.
I still think it's neat, but I just don't think it's quite what many seem to make it out to be.
