I always break-in my vehicles on the hard side. I don't mean beating the crap out of them, but I do get on it pretty good. I was told by a teacher for ATI (Automotive Technical Institute), that you really want that motor to "learn" it's tolerances early. Made sense to me. I love the power of my Hemi in my Ram, so the Daytona should be awsome!!!!! I guess I'm a converted GM guy. My last 3 vehicles have all been Mopar. 2 Dodge Ram trucks for work, and awaiting my Daytona. I guess it Mopar or Nopar.....
