In the end, and I think someone has already mentioned it, an engine that has the lowest horsepower per liter is likely gonna live the longest....all other things being equal.

You have a Lehman 120/135. And you have my Cummins at 330hp. They are almost exactly the same displacement(6.2 vs 5.9 respectively). I would expect almost 2.5 times the hours out of the Lehman than the Cummins.

Somebody mentioned rating an engine based on how many gallons have been run through it. Same thing since fuel/heat/energy pretty much equals horsepower.
