On a day with some light drizzle I was setting the valves on my 427 Nova. While tightening the valve cover bolts (engine running) with a 3/8 drive ratchet I noticed one of the ignition wires was laying right on the headers. As I lifted the wire up my finger went into a hole burned in the underside by the hot pipes. As 50,000 volts of CDI spark juice went thru my (bent over the engine) body, I turned into an instant surf board with my head smashing into the underside of the hood and the ratchet swinging around hitting me in the eye. When my friend got out of the car I was flat on my back in the road making invisible snow angels.
