MSD Coil degrade?
10 or 15 years ago, I replaced the stock coil in the distributer in my 76. I felt the power and throttle response difference right off the bat. Does a modern MSD high output coil degrade in time like the stock GM coil did? I have a ZZ-4 with MSD wires, 6AL box and the GM distributer that came with the ZZ-4.

My experience is that aftermarket high performance coils, of whatever manufacturer, don't last as long as the original GM HEI coil. I'm not sure the aftermarket coils are better in any regard.

wasnt bein sarcastic, 5-8 years on a coil no matter who makes it is pretty good. they heat up and cool down...alot , and over time build up resistance and break down inside

Now that's good insight. I know you weren't being sarcastic. I had the car dynoed and they didn't say anything about replacing anything. What you said though makes sense. Thanks......
