These are some serious fighting words. With a few basic reliability mods the 6.0 and 6.4 are excellent motors that, when properly maintained, will pull right there with the chassis for ages.


Then I'll take the fight... the 6.0 (especially) is junk no matter what you do. Any motor that you have to pet and pamper doesn't belong in a truck. The 6.4 is certainly better and yes it pulls like a hoss... but IMO its still not in the same reliability class as the old 7.3 Powerstroke. I will dispute the first poster who includes the older IH engines like the 7.3 Powerstroke as "junk." The 7.3 Powerstroke / IH T444E is an excellent powerplant. I'd still rank it below the Cummins in longevity, but that was just part of its design- lower initial cost offset by shorter life. But frankly, its lifespan is probably better matched to a pickup truck chassis anyway.

The old '95-2002 7.3 powerstroke was ok, but I'd still rather have a Cummins!


Back to the 6.0 powerstroke, that motor was so good that Ford had to buy back 12,000 trucks and sue International for warranty cost recovery. They ran the 6.4 powerstroke for 2 years, then told International to shove it, Ford built the new 6.7 in-house, we'll see how it does long term.

I think Cummins will be a victim of their own success - this iteration of the ISB is treading into ISC/ISL turf! It has as much torque as the ISL bus engine!

The ISB is a popular bus and pickup/delivery motor as well. It's used in school and hybrid transit buses, it has found an home in countless UPS/FedEx vans and bread vans. And yes, tractors as well.

Keep this in mind: the ISB typically isn't cranked up as much when used outside of pickup truck applications. Same goes for all the pickup diesels (older IH powerstrokes in particular). Typically, being that lifespan is a little less important, the pickup versions rev a bit higher and make more power.

+1, I've been driving the 08 Ram 1500 Lonestar 4.7 again for the past week.

I think Ford may still have a slight edge in sheer number of trim/powertrain combinations, but Dodge (still rebelling against just saying 'Ram') has reeled them back in overall and still has the best diesel by a good margin. They don't a clear superiority in light trucks like they did in the mid 90s when the re-designed Ram up-ended the whole truck market, but they're definitely up in Ford territory again.

i'll introduce myself by jumping into this fight........the numbers don't really lie when it comes to the 6.0 and 6.4. catastrophic failures are far too common and it's unacceptable, so much so that for axed navistar engines... and the idea of saying "with a few basic mods these are good engines" makes no sense at all. how is spending $5k to upgrade a a $20k engine just so it will live under normal conditions sensible? i can go on on but you get the idea
