Yes a 400hp LS1 will outlast a 400hp rotary. The idea was what if they both made the same hp/L then how would they compare. We are talking about engine stress. Would a 877whp LS1 in a vette fair as well as for a dayly driver?

I still think everyone is missing your point.

hp/l IS a valid argument from a physics stand point. Is it how the public looks at hp, no, but it is a valid argument when it comes to reliability and how much stress an engine will take. A 400hp LS1 is not near as stressed as a rotory, 2.0l I-4, 3.0l v-6 etc. So an equally powerd LS1 is more reliable. All CW is saying is, would a 877whp LS1 be as or more reliable than a 400hp rotary?? It's not how much power you can make or is a rotary better than an LS1. You could use a 5.0 ford or a 5.9 chrysler in the same argument, he's not attacking LS1s, they are just the typical swap.
