Your ignition switch will be easy to test. Use either a test light or a volt/ohm meter to verify that you have voltage on the output side of the switch when it is on, at all times.
Do you have, or can you borrow, a known good MSD box? I know they say it passed their test, but I still suspect you have a defective box. The reason I say that is that if I remember the sequence of your problems correctly, the car would actually start and run, until after you dropped a wire or otherwise shorted the MSD box. For that reason, I am very suspicious of that MSD box.
Don't stand on your head, your glasses will likely fall off, and we know where that will leave you.
