MSD 6a vs Pertronix III


Recommended Posts

Hi All,


I've been doing some reading about multi spark ignition system. From what I've ready they are a good upgrade for our cars. Mines a Federal S1, still has Strombergs and 25D distributor with Pertronix I. It has a bit of trouble starting when cold but starts easily when warm.  It seems a lot of people have installed the MSD 6a, and say it improves cold starting and idle smoothness.


I was wondering if anyone had any opinion on the Pertronix III. Seems nice that it fits entirely within the distributor.


What do you guys think?
