I am putting a 600HP Big block in the Dart (I know thats not the most weight transfer friendly combination), I had a 3/4 ton truck Dana 60 and a C-Body 8 3/4 laying in the garage. I figured if I was going to cut a rear down and fit it in the Dart, I might as well use the D60. Sometimes I get really stupid ideas and if I go to the drag strip and end up mounting a set of slicks on it, I do not want to have worry about breaking anything.
