It went pretty well for a first drive. The idle is a bit high, and there is a little hesitation for the first 1 or 2 percent of pedal travel. But those are both tuning issues. My friend and I drove around his neighborhood several times, kept the RPMs below 3,500 or so, and went through the first three gears. Car drove very nicely at cruising speed, and had no problems with light acceleration.
Once I finish the tuning process, it will most certainly have been worth it, both functionally, as well as for the giant feeling of accomplishment I am feeling right now.
