Seeing if this cam is good and if it will work

By your screen name you have some particular year Dart with a 318. Everybody always pops the hood and starts thinking about doing something for more performance. I say jack up the rear end, determine what gear ratio you have, and research what it takes to swap in a more performance oriented gear ratio, and Believe what some others here are saying.
Pop the hood only to tune what you have at the moment.
