We started out with this 2002 Ford F-250 project truck with a challenge to take this strong 7.3L engine and create a fuel-efficient, towing machine. The 7.3L engine is a legend in the diesel industry because of it durability and versatility, and that's why we picked it for this build. We knew going in that with a few specific upgrades, we could take our older Ford and breathe new life into her. We quickly dubbed our Super Duty Big Blue, based on its raised look and color.
