Thanks Tony. I already did that. Any wire next in the firing sequence can cause crossfire, especially when the wires are routed next to each other, such as 7 and 8. That's crossfire cause by inductance. I am pretty sure my crossfire was from bad wires and caused in the dist. Closest terminal to rotor may not be the path of least resistance due to bad plugwires, so spark jumps to next terminal. I did the "midnight" test and saw no arcing or corona, but I changed the plug wires anyway and the crossfire is gone. Just left with the mifire.

Misfire is only when really hot out, so I am waiting for more hot weather to do another test. So far, switching back to points seems good, but time will tell.

I did a Google search and found one guy in a British car forum who had the same problem. Replacing the Pertronix system with a new one fixed it for him. So I have hope......
