It's starting to get really exciting. The crew at Gateway Classic Mustang is on a very tight schedule so they've called in some backup to help finish Chad McQueen's Bullitt Mustang. Michael Manning of American Auto Wire has the huge challenge of creating an updated and modern electrical network for the entire car. David Gravley and Mark McDonald from Year One are on hand to lend their expertise. And Jesse Kershaw from Ford Racing is in the shop doing some last minute modifications on the Boss 347 engine. With all this help, the crew makes some major progress on the build, installing the shocks, engine, transmission, electrical, sound system, air conditioning, dash, and instrument cluster. It's finally time to test fire that Boss 347.
