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

yes. For a true bracket racer, a gutted car with 4.56 gears, 3500 stall, and a 500 dollar motor is all that's needed. You can easily run 12's, be consistent, and never break parts. And if the motor has an issue, by another 200 dollar FBmarketplace magnum, throw the intake/carb/oil pan on it and keep truck'n.

That may be all YOU need but for others it not.

If that were true there would only be bracket classes.
