One problem at a time. You say when the engine doesn't turn over you hear a click. Is that correct? The click you are hearing should be the starter solenoid trying to engage. The solenoid is nothing but an electromagnet . It pulls in a cylinder than engages a copper washer that transmits powers to the starter motor windings. When engaged this copper washer gets its power from the battery cable. The back side of the large starter lug that the battery cable is attached to inside the solenoid is copper. When the two copper pieces come together they will burn over time they become so burnt that the solenoid will click but no electricity will flow thru them so the starter motor won't turn over. Repeated trying to ingage the starter motor sometimes gets the two copper pieces to make contact and the starter motor will turn over. So try a new solenoid. Second problem only less than 9 volts at the distributor. Remove the bulk head connector, find the end of the distributor positive wire, disconnect the positive wire and measure to see if there is any resistance on the wire. it should read zero. If there is any you need to find out the problem in the wire and fix it. The wire should be at least a 14 GA for an HEI.
