Hard to beat good ol MSD. Readily available and lots of info. Nothing wrong with Factory either. As for the rest of it, it may be worthy however I want support a d repair options if necessary...
Can't prove that by me. Had an MSD box on the 64 Barracuda and started having problems, so I put the old Chrome box back on it, and it was a whole new car. Trashed the MSD box and never looked back. And that was in the 80's or 90's.
