stroker kit lol...ive never heard of it doneon a new challenger, but making it a 372 stroker would be amazing lol.....plus they've done a lot of tests and the srt8 and r/t r not far off in performance...im sure highway racing is when the srt would show its colors, but not much is needed to bring an r/t even faster than srt...heres a link http://www.youtube.com/watch?v=qCNUsUQRC0c
