Stronger i have pulled a head off of a 95 12v that a pipe tap went through all it did was hit the piston and get stuck in it we drove the truck after the pipe tap broke for almost 100k pulled with it everything we could ran great. Ive seen 06 cummins blow up if you look at them wrong. 6.7 liters in my opinion cannot be that strong but only time will tell

Comparing a 160 HP engine to 325 HP emissions motor doesn't give a true view of the capabilities. A CR takes more abuse in everyday driving than a 12V does when you hammer it. If a CR is having issues something is causing cuz the bottom ends are pretty damn good.
Aside from the siamesed block, the 6.7 is a good base to work from. The elctronics on the emissions pieces are the single biggest problem but the base engine shares about 40% of the parts with the 5.9 so its solid.
Still not enough data on the siamesed cylinders and the potential for problems under different conditions. Thats a big unknown at this point.
A 6.7 can run under the 5.9 electronics and work quite well. Even some swapping of heads and injectors can be done with some caveats.
