I'm completely stumped/pissed/miffed/lost.

The problem....driving in pouring rain 7 days ago at 75-80 MPH and the car just shut off.

I have spark (confirmed by wire off coil and watching it arc)
I have gas (confirmed with filter off and looking in the carb)
I have air (cause I'm breathing)

Car still won't fire.

It just cranks.

It cranks just like it would if the MSD controller wire wasn't hooked up to the distributor, but it is.

I can't find my owner's manual and MSD site is kinda useless, I remember there is a way to test that the box is working by using a clip in the distributor wire, but I do not have the details on it.

Looks like I have found the problem.

The magnetic pickup appears to not be working in the dizzy :(
