Wow! My hope (Guess) is that the piece was blown out through the valve and smushed the plug on it's way through. I once dropped a little washer into the carb with motor running and PING, came out the header and hit the back of the shop. Only damage was that bent spark plug... whew

Subject: Found the problem
To recap for everyone: On the eve of the Geezer Drags I drove my car to Rich K's house to socialize a little. The engine started to miss, which was pinpointed to #4 cyl. Discovered that the neg. electrode had been hit by something and bent over. There was also a bit of a noise in the engine.
Since I am now retired as of last week, I took time today to pull the head off. Discovered that about 1.5" of the top ring land had broken off of the piston. So looks like the engine is coming out. This is disappointing in that I probably only have about 1500 miles on a fresh rebuild. And it has only seen 5K rpm a hand full of times in that time. The pistons were new KB Hyper-eutectic's.
Somewhat surprisingly there was no debris left in the cyl., and no apparent damage to the head. Still need to check the make sure that the valve seats are not damaged. I'm attaching a picture.
