The stock Ford stuff is really good believe it or not.
MSD models most of it's ignitions after Ford technology anyway.
I never saw the point in replacing a Ford distributor with an MSD distributor that was just a copy anyway. ???
Ford igniton is already captive discharge, but some of the multi-spark boxes are interesting, to me anyway.
Just have to know what you are getting. A C/D box is just duplicating what you have, so if you go with a box, make sure it is multi-spark.
Then you look at the details from there, most only operate as multi-spark below 3k rpm. Some are as little as 3 sparks per rev, some as many as 14 sparks per rev. MSD boxes (the ones I have used) are only multi-spark to 3k, then go to single. There is one brand that is 14 sparks per, until 3k, then goes to 3 sparks per after that. I forgot the brand, but that is the one I would get if I were in the market for a box.
Most coils are no better than the Ford part unless you go to a "race" part, and then risk overheating the unit by driving it on the street.
