I don't think a 5.7 charger would gain another 20 mph over the Magnum since they are basically the same platform. My 6.1 Magnum has a little bit more power but the gearing is more for bottom ends not top end and that's why I would want a little bit taller tire. 5.7 cars were 2.82 gear and 6.1 cars were 3.06.I'm not sure if you ever ran those speeds on the street or if it was all on dino stuff but I would think that there's a bit of a difference between the two since the dyno takes out aerodynamics and weight I would think. Yeah the 6.1 has quite a bit more power but it is also not as aerodynamic and with me in it would weigh probably 4600 to 4,700 lb if I could take some of the additional weight out of the interior.</blockquote>
