I‘ve noticed a shift over the years in recommendations for ignition systems to the DS11. Technically, what makes this superior to the other choices? One of Mike’s articles touted the HEI as a “better” system: https://fordsix.com/ams/ignition-system-choices.13/ . My experience with the DS11, when I was a mechanic, was less than ideal going so far as to install a back up module on rental vans in case the original module gave out. So please discuss what is a ’best’ ignition system from a technical standpoint without regard to appearance, etc…
