Sounds like the ignition is set up for a ballast resistor, but the
direct connection (that is provided while cranking) has failed. In a
ballast-resistor setup, the coil is built for a lower voltage. The
ignition switch is built to provide a direct connection when cranking
and a resistor-protected connection when not cranking. If the system is
wired wrong so that there is a direct connection when not cranking, the
coil may become damaged by the full 12v+. Check at the ignition switch
to make sure the connections are all good, then check to see where the
direct 12v+ connection (while cranking) has been lost. Since you have
the full 12v+ while not cranking, perhaps the connections at the switch
have been reversed and the resistor or resistor connections have failed.

I just use a short 7/16" box wrench. If a hex won't allow you to loosen
them, perhaps a 12-point will work. I think the fasteners should be
7/16" since I'm fairly sure LBCs didn't use metric.
