I ran one on my Dart for a short time and it was super responsive and ran pretty well after putting my tune up in it but I sold it and went back to a 1050ish Dommy and was much happier. Not that it's a bad design at all and actually it was TOO responsive a peaky down low making traction a b%^&h and why I always go bigger than some on cams and carbs to move the power band up some and making traction less of an issue, kinda like adding duration to your cams......
