We are talking vibrations, the human ear cannot recognize a knock vibration from regular engine vibration. It cannot be done. Period. End of story.

And like blueguy said, if you can hear knock, you're absolutely F'd.

Rocks shaking in a coffee can sounds like a bad coupler to me.
exactly, since you dont have points, rotors or caps or a distributor, none of that crap can be heard. if you do hear that, park the car and set it on fire, its past repair lol
