Someone in the Duramax vs. Powerstroke thread stated that an inline engine (in that case the Cummins) would outlast a V engine (in that case a V-8 diesel).
I've heard that assertion before; inline engines are more durable than v engines, but I'm wondering if that's folklore or fact. I do know that the old 300 I-6 Ford made was their most durable. Also the old GM I-6, ie 292, was a workhorse. Is there any real evidence to prove the "I" better than "V" argument? Have you seen that to be true in your experience? Is that why GM is moving to midsize I engines, ie I-6 and I-5?
