I have checked the timing and its all good. When I put the light on it the miss shows up on the timing light. That tells me it's electrical. I don't know what I could do to help. Now it seems to be killing coils. Second was just replaced. I need help. Thanks Mitch

 

I hate to bring up something you already checked but I always double check that my wires are seated all the way. I actually did get one pushed down but not connected one time.
Also you want to check your vacuum advance and the line. Make sure that is still operational. Might as well check gaps on your plugs too. At least we don't have a V12 engine lol.

As far as killing coils that might be a short with old wiring or it could be a distributor going bad? I haven't ever had that problem but you're right when you say it's electrical.

I'm probably beating a dead horse but I always recommend LC Engineering. If you give them a call I'm sure they could help with the suicidal coils as well. Hope this helps Mitch.
