Could my 340 block be filled?

Old gms use to mount tower pointing down.
Best bet is epoxy filled coil.

I put my new MSD coil in tonight and another ballast resistor. Fired her up and let the car warm up for a while. Set the timing and went for a little joy ride. Put the car back in the garage for about 10 minutes and I put the timing light back on it. Turned the key and I am right where I have been for a very long time. No spark when I go to fire her up......the ballast resistor was extremely hot.....like 200 degrees hot...the wiring going to the ballast resistor is totally half assed like most of the car has been as I try to fix things.....It looks like 5 wires going to the ballast.....one side has 2 dark blue and a green with yellow trace....the other side looks to have 2 faded red wires
