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

I would personally never race anything slower than 6.50 probably. I care more about having fun and going semi fast than I do winning. 6.0’s to me is fun. Semi fast but not crazy fast and I can still do it on a budget.
This in a nutshell is why I hate bracket racing most of the time. A guy can jump in a 17 second minivan and clean house on a whole field of fast, well built cars and all he had to do was cut an ok light and leave it in drive. For me winning that way is like being proud of a getting a trophy for participation.
