If it's running good then do everything else you want to do. If you do have an ignition failure then replace it with a $170 gm performance new distributor and your done forever. Msd and the other ignition systems do not add anything to a driver. In my opinion not much to a performance car until you get into high end drag race applications. I Install hei's in my street performance customers cars and trucks up to 600hp. Reliable is the key to a driver.
