I grounded coil positive to block?

I don't get this. If the OP is running an MSD CDI box, I'm not sure how grounding the coil would cause all this mess. The coil+ on an MSD 6 or other CD box is not connected into the normal power feed like it is originally.

In any case you need to troubleshoot each problem "on it's own" and do some actual troubleshooting, not guess

The fuse link is not open if you have power "in the car" such as dome, headlights.

So start with the feeds into the engine bay. There are only 3 to worry about

1....Ignition run, or IGN1 comes from the key "run" contact, and feeds some things in the car such as cluster power, and goes through the bulkhead originally to the ballast. This should now be connected to your MSD "small red." So with the key in run you should have power there This is often dark blue, refer to your shop manual, not all years

2....Ignition "bypass" or IGN2 bypasses the ignition resistor and is the only ignition power during cranking. With the key twisted to "start" the MSD "small red" should also be hot. IGN1, above, goes dead in this function

3...The normally yellow "start" wire. This comes off the key, is hot ONLY in "start" and goes through the bulkhead to one of the two small flag connectors on the starter relay. Check with a light or meter, this should be "hot" with the key held in "start."

From there, power goes through the starter relay coil, (magnet) and "comes out" on the remaining small flag connector. From there, it is grounded in park or neutral by the neutral safety switch, or if stick car, is grounded by the clutch safety switch.

You need a service manual and or wiring diagram if you don't have one. I've posted this a xillion times. Go to MyMopar and download them for free.
