Personally, I have never had an MSD failure. I did have two Dura-spark boxes eat it. So I chose to run a redundant ignition system straight out of a Winston cup car! (Gotta love EBAY! I paid like $370.00) It was a beautiful part, Two HVC 6 boxes, two HVC coils, Deutsch connectors, rev limiter, noise filter. I cut the mounting plate to fit the car and wired it using the tech info on the MSD web site.
It’s nice to just flip a switch and be on a whole different system.
FYI there is a similar Crane based rig on ebay right now
