67 twin turbo dart

I’ve struggled with similar issues the last week. My sensor(3rd now) just died out of nowhere. Have you checked your gap every ~90°? My hack job toothed wheel has around .02 runout so I’ve hit the sensor after setting the gap on a low tooth. I suggest not following the recommended gap and bring it closer like others have suggested. What stands out the most to me is your cam log. Mine produces a square wave from a the half moon distributor wheel. Has your cam log always looked like that?

I’d also check crankshaft end play…just in case.
