Re: 6.0 life expectency?
There are several life expectancy ratings, B10, B30, B50. If a manufacturer wants a high number they quote the B50, lower milage will result if they go with B10.
Don't quote me on the exact wording but the BXX refers to life expectancy with recommended maintenace that XX% will need a major repair. Major repair being cylinder head, rings, bearings, etc. i.e., repair requiring substantial disassembly.
Cummins 5.9 and the IH 6.0 both have the same rating when compared B number to B number if you dig around the respective engine makers' websites. Those numbers would reflect the commercial versions of those engines which are not exactly identical to the Ford and Dodge versions. Pickup versions are turned up to higher HP and Torque but will likely see much less high load use as compared to the same engine used in a MD truck running the detuned versions of the engines. So the higher output likely won't negatively impact lifespan compared to the commercial versions' ratings.
