Bad plug wires might make a popping sound as the voltage jumps to ground but it isn't what I would characterize as tinkling.
With a high compression engine I have blown the porcelain insulator out of the engine with detonation, but I haven't as of yet loosened the grip of the crimp on the plug: though my plugs never lasted long, either fouling, or burning up.)
That stuffing is fiberglass that is imprgnated with carbon dust to make the conductor. They are cheap and do not last long. They also have incredibly high resistance).
I use solid core wire that is spiral wound to prevent EMP from affecting your neighbors TV or Radio signals (I also do it because I like to listen to classical music on my stereo FM radio while I cruise). So there is no popping o crackling in the reception due to solid metal conductors.
You can get modern spiral wound 8 mm spark plug wires in black, though not date coded Packard wires, look more correct than neon blue, red or yellow wires. The most period correct look would be red booted yellow Accel wires an Accel SUPER coil on the fire wall with a Mallory dual point distributor, and headers painted flat white.
