360 Swap for the 65 Dart

under acceleration the vibe is there? Could it be a miss or a poor plug wire? I never had the smoothness of my 273 4bbl with any of my motor transplants, although a stock 225 was butter smooth at idle but I never got it out of the garage in its stock state. I still remember those bias ply polyglass tires and the 1 finger power steering.....ahhh. :-)
