Updating the ignition system
An anecdotal input......
I have an MSD 6-C (has the Chrysler 5-pin connector) unit on my car. It has worked flawlessly for over 25 years.
I do remember the difference that box made in starting the car when I first put it in. It takes no more than a touch of the starter..and the engine is running.
I can't tell you the joule rating or the ยบ duration of spark it puts out. I would imagine that newer units do 'more'.
Combine 25+ years of use with the fact that it does a good job..I like it!
