You said that you installed EI. I assume from Pertronix? Did you get the full kit with a new coil? Are you running the old-style copper plug wires or did you also upgrade them to modern ones? I don't think the old solid copper plug wires are suited for EI but you could ask the Pertronix folks to be sure.
