GM owns the controlling interest in the Isuzu Engines division - and the Duramax was designed with a lot of input from U.S. GM engineers. So, you can really say GM hired "out" for it. Also, as I recall - the changeover to the Duramax was partly due to the emissions regs and problems dealing with an indirect-injected diesel like the 6.5.

In regard to V-8 diesels in general - an inline ladder-frame block is inherently stronger. But, there are still many very strong V-8 diesels out there. The IH 445 (7.3 liter) and the somewhat larger IH DT466 are pretty durable and have "B" heavy-duty ratings as good as the Cummins 5.9.

Sometime probably next year - there's going to be a bunch of new, lightweight V-8 diesels coming out - from GM, Cummins, and Navistar. Many will be available in 1/2 ton trucks and SUVs.
Cummins has a new 5.6 liter V-8 diesel with a "B10" rating of 325,000 miles - that means 90 % will make it that far, and 10% will not.
The Navistar Ford 6.4 V-8 has a B10 of 262,000 miles and a B50 of 375,000 miles.
The Navistar DT466 V-8 has a B10 of 300,000 miles and a B50 of 450,000 miles.
