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

Or racing for 20 plus years and racing in the “street” class. We have a longtime Mopar racer beating up on beginners and he’s prouder than a Peacock. Guys and girls that are beginners get discouraged and quit.
Kind of like the guys here in stock car racing building 50 thousands dollar entry level thunder cars instead of a couple classes up where that money makes sense, guess there happy being a big fish in a little pond.
