msd or mopar hei ?

Oh no, we are going to start this one again. Guys lets keep it wrapped up with some will have problems with MSD (Rumble) and some of us will have problems with stock ignitions (Me). I honestly think it is a matter of what does the car want! We all know that they have a mind of their own. You won't know til you try something if your car will like it or not. It seems you can ask 100 people and you will get 20 different responses about what to use and why and what not to use and why.
