Ford 272 C.I. runs low 11's. Why do Mopar guys need 408's?

Not saying to build it, I found it interesting, and thought the guys talking about polys would to.
Yes makes more sense to build 340/360 408/416 400/440 470/543 and people should but it a boring read most of the time. It's like nitrous dyno pulls add 100 hp nos shot and get a 100 hp more power big surprise.
Tossing anything in the ring is what usually happens. LOL
Only big blocks I'd build would be 400 based
