In the Big Diesel and Drag Truck series, Bill Carlton and his crew fit a new engine into a 1937 International Harvester. They also convert a 2005 Chevrolet Colorado into a nitrous‑infused drag truck, giving the vehicle a fresh purpose.

Big Diesel and Drag Truck is a programme that presents its content in a single‑episode format. The show centres on automotive projects, showcasing the work of a specialised team as they tackle both classic restoration and high‑performance builds. In this episode, Bill Carlton leads his crew through the installation of a new engine into a 1937 International Harvester. The team dismantles the old power‑train, fits the replacement, and reassembles the vehicle, aiming to bring the historic tractor back to operational condition. At the same time, they turn their attention to a 2005 Chevrolet Colorado, converting it into a drag‑ready truck by adding a nitrous‑oxide system. The episode highlights the contrast between reviving a vintage piece of machinery and pushing a modern pickup to its limits on the drag strip. By working on the International Harvester, the team demonstrates the careful handling required for older equipment, while the nitrous‑infused Colorado illustrates the kind of performance upgrades that can dramatically alter a vehicle’s capabilities. Overall, the programme offers viewers a look at two distinct automotive endeavours in one sitting: a meticulous engine swap for a 1930s tractor and a high‑octane transformation of a contemporary truck into a drag‑focused machine. Both projects are carried out by Bill Carlton and his team, providing a clear snapshot of their expertise.
