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

Who said anything about weight? Not me. I was talking about header fitment, engine mounts, ease of spark plug removal, trans has to change, etc. where a guy with a 318 could build a 408 and drop it in.
unless it's a early A, then the RB fits real nice with under chassis headers and plugs are a snap to get to :poke:
