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

A 500hp 408 is a pussycat of an engine. Can be driven all day. A 500hp 318 is an entirely different animal. It’s just so much better to start with more cubic inches for a street car. And the aftermarket makes it so easy to buy a kit and drop it in.

And a 500 hp 543 would be super daily driver making the most 1000-5000 rpm hp/tq so?
It's all what you like @66fs likes the power and powerband of his 300-350 hp 273 over a similar 360 others wouldn't most of this is personal preference, most the arguments 408 guys make if followed would have a 440 to 540 in their car. Funny it ok to build a relatively small 408 compared to 500+ cid engines but not a 318.
