WIW All Original 74 Duster 360 4 Speed Car?

NO. That 360 Duster had some better flowing heads and a slightly bigger than stock cam added. It would do low 14's at the pure stock drags. My 340 Cudas were in stock form, ran close to the same. My point is with enough changes and money you can make em go faster. They aren't turtles by any means.
