The Ford ignition is much more reliable. The MSD continues to be Mysteriously Sucky Devices and will leave you stranded in the middle of nowhere for no apparent reason.
I only went through four MSD units before I saw a connection?
They seem to like low humidity climates like Texas, Arizona, Nevasa, Southern California the best.
They do not like the Norheastern US much at all.
Racers swear good by them but racers tend to change them out a couple of times a year or more which is my experience with them on the street.
Your mileage may vary?
