Where's this noise coming from?

Been busy moving in all weekend. I haven't had time to do anything car related, but the plus side of that is I can access my tools! I'll break out the timing light when I have more than a couple minutes. :D

I stopped by a local shade tree mechanic on Friday. He and his buddy said it's spark knock and that I should change the wires to correct it. Is that right?

Change the wires to correct spark knock???? That's the craziest thing I've heard in a long time:violent1:. Not saying you don't need new plug wires cause I haven't seen your car but wires aren't going to magically make spark knock go away. Spark knock is caused by either the timing is too far advanced, carb. running lean, engine running real hot, fuel that's too low octane rating. Oh yeah, oil consumption can also make it spark knock. That's about it.
