That sound, as you describe it here, reminds me of a spark leak that I had in one of my old V-8s. The sound was more like a click or snap that would easily get drowned out as you rev the engine. I tightened down all the plug wires - found one was very loose (stupid cheap wires - I was poor). The spark was jumping the gap from the wire to the top of the plug & made the snap noise. The engine ran just a bit rough because of it too.
Must be that jumbly-wumbly thing happening again.
