The power to the coil does not go through the fuse block. Instead it goes through the fusible link at the solenoid and then to the ignition switch.
Do you have the factory tach? If so, the power to the coil goes through it, from the ignition switch, then through the resistor (pink) wire, and then to the coil. When cranking, 12 volt power from the "I" terminal on the solenoid bypasses the tach and resistor wire to provide full battery voltage to the coil.
If you're not getting power to the coil when the key is in the run position I would start with the easiest access points, such as the fusible link. I would also check the voltage on the solenoid "I" terminal when cranking.
