So this was it. This was the day. Wait for it...
First thing I did was bleed the brakes again. It had a small leak at the 90 fitting that goes into the tunnel from the front. I tightened that up and it held pressure perfectly.
We put the decklid and hood on. Installed the passenger seat and the tires, then....
Drove it! Yup. Big day.
Here's the videographic evidence that said event actually took place.

You'll note that it sounds much more like a Porsche than a Chevy.
