10 Day Magnum Swap - '65 Dart 270

thats like installing a sun roof in it.....you will hate yourself in the morning, or at least next time it rains:rolleyes:. Unless I was installing more than 325 HP, I would stick with the 273 manifolds. I cry every time I go check out a car to build and it has/had fender well headers, then I head home with an empty trailer.
