The Ridler car's engine and transmission are married for the last time and installed, and the team moves on to the wiring and other systems. As the car is prepped to fire up for the first time, a dent threatens to stop the whole build in its tracks.
The Ridler build arrives at the Autorama, and at the initial drive test, Dave and Kev scramble to fix a transmission problem. The next day, the show opens to the public and the judging begins. It's also their first chance to size up the competition.
