Ping is also known as "Pre-Ignition". Your cylinders firing BEFORE the plug actually fires it. Possible consequences include, but, are not limited to: Broken pistons. Melted pistons. Bent Rods. Etc. All VERY expensive repairs. You might be able to slide by using a higher octane fuel, but, fixing the root cause of the problem is your best bet.

I've never actually heard of an engine being ruined by pinging, but it can't be happy about it. After all, the pinging is caused by the flame front hitting the pistons while they're still on the way up. It's my understanding that the sound is caused by the rattling of the piston/wrist pin connection. You might want to run premium gas until you can eliminate the cause of the pinging, and/or try to retard the timing a little by moving the crankshaft position sensor a little. I've read a few threads on here about slotting the CKPS bracket so you can move it a couple of degrees.
Question: You mention that you have a 25% underdrive pulley. I associate those with superchargers. You got a blower on that thing? If not, what's the purpose of an underdrive pulley? My best guess would be to reduce the amount of power used by the fan.
