Ballast with Pertronix?

The question of ballast or not, depends on what coil you're using. Pertronix sells a nice high voltage coil or we often use a Bosch Blue Coil. Neither of these need a ballast. If you're using an original style Marelli with the piggybacked ballast, you will want to leave it in place.

If your original coil is very weak, you will notice a small improvement. Simply changing to a Blue coil will not add 10 horsepower, if that's what you mean.
