If you are only getting spark to a few cylinders by checking each with the timing light then you have a problem in the distributor as each wire should make the timing light put out a signal. First off, I don`t know what year vehicle you placed it into, but the HEI must recieve a 12 volt signal, so check the power wire running to it for 12 volts constant. If that checks okay then it could be anything in the distributor from a bad cap to bad wires to a coil, pickup coil or module going south.
