1984 Chevy Camaro engine jumping fire, HELP ME!

I have a 1987 s10 that has a 1984 camaro motor in it. My problem is when you crank it (it can only be seen at night) there is fire coming out the wires down at the plugs. Also if I touch the wires I draw fire out of the wires, (its a little glow on my fingers) or if anything that is metal and grounded touches the wires fire will come out. Now it won't shock me there, so I don't understand it. I can touch the coil wire where it plugs on and a little glow will be on my finger. Its like this if something touches the wire, if it just a hair away it won't do it, BUT THE WIRES ARE ALWAYS CLOSE TO SOMETHING METAL UNDER THE HOOD. But it shoots a glow of fire down on the plugs while its running ALL THE TIME. I have replaced the plugs, the wires, distibuter cap, and rotor button, and it still does it. Please help me as soon as you can, thanks.
