What do you think about this statement.........

I've seen a 5.9 in a Van in the local area that had 435k miles on it, long block never taken apart. Couple timing sets, water pumps, starters, but nothing internal. My 5.9 just turned 322k this week :)
I totally understand somebody preferring the LA's. I too, like the rocker shafts. But, it's just pure prejudice to say magnums aren't good engines. And the magnums have absolutely proven on the drag strip they can perform with any LA.
