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

the OPs title of this post seems flawed. There are LOTS of mopars way faster than 11s that are smaller than 408. I recall a dart 30 years ago in my area with a 273, it ran 10s in the 1/4.

Without a power adder, I find that hard to believe.
