67 dart stroker hellcat gen3 hemi with twin turbos...

the coil wires and even spark plug wires touch nothing on the harness. even several inches away from anything besides themselves. probably 6plus inches away from the crank sensor and 4in from the coil harness till the harness reaches the coils.
They don’t have to touch and you can’t move them far enough away from each other. That spark energy can jump all over. Do some research on plug wires and RMI.
