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

No, poop was the exact correct word.

Until you have personally tuned something fast you should bow out and talk about what you know.

The quicker and faster a car is the harder it is to tune. Margin for error gets slimmer by the tenth.

One last thing. If you think your 20 second van (or whatever it runs) is more affected by a head wind than a 8 or even 9 second car you need to study some score and physics and then do the math.
fixed again ^^ LOL.. How about we talk about what we show?? I just showed how to hook a 12 second car in street form with a open rear end :) Means you brought up "12's"
