Looking for a solution to my misfire. My ignition system is m s d pro billet distributor blaster 2 coil and 6a box.cylinders 5-7-8 are not firing all the time . I pulled all the plugs and 5-7-8 were wet did compression test on all cylindercs all good there put new plugs and wires in. l Still have a misfire I am leaning towards the coil,any suggestions to look elsewhere

I think the MSD stuff is not all that good, I run a replacement stock dist.,a motorcraft coil( replaced anMSD gone bad)and daily drive for the last 14 years with zero misfires. If you have stock parts on hand switch 'em out one at a time and may the Swartz be with you.
