a couple of suggestions: old yellow wire that gave power to dist must be replaced with a new wire right from the fuse block. yellow wire is under 12 volts, not enough for hei.
make sure you put carbon center piece in cap before rubber washer, if washer is installed first will cause pole to be too short.
look under rotor. if you see a burnt mark in center replace it. spark can arc right through rotor
to check pick up coil, pull on the 2 wires. if 1 stretches its broken inside insulation.
