Day 5 recap. With 90-percent of the build behind us, it’s the remaining tasks that are going to be the true tests of patience and will. The most important task of all—the firing and subsequent tuning of the C10’s ZZ6 small-block—was met with a round of applause just as it was crossed off the to-do list early on Day Five. United Pacific took the electrified opportunity to complete the installation of their LED lighting components, from the 7-inch headlights and amber running lights to the sequential taillights. The wheels were finally dropped off with their new Continental Extreme Contact Sport tires mounted so we could get the C10 down on all fours in preparation of its first test drive later this evening.
