The "iron duke" was an extremely durable engine design. Old technology, yes. High performance? no. It was essentially the original Chevy II engine from 1964.

Not above and beyond what is in the owner's manual. Just that virtually ALL driving falls into the category of "extreme service" according to the manual - and if you service the car as "normal service" you are SO SCREWED. Service as "extreme service" and the engine lasts just fine, thank you very much. Same with the Toyota and Nissan vehicles that had the "problem". Maintain them properly, and no problem.

Again, hogwash. Hundreds of vehicles used in all types of severe service and getting 6000 miles changes prove it.
