In this thrilling episode from MotorTrend Channel, we witness the epic saga of the Mobark Muscle Truck, a 1974 Dodge D100 Stepside, as it undergoes a jaw-dropping transformation. The host's unwavering passion for this iconic Dodge truck generation, particularly the short bed Stepside model, shines through as he recounts the challenges faced during the project. From acquiring the truck for a mere $900 at a wrecking yard to experimenting with various small block engines, including a 318, 360, and 48, only to face repeated engine failures, the journey is nothing short of a rollercoaster ride.

The pivotal moment arrives when the decision is made to swap out the troublesome small blocks for a cutting-edge Gen 3 Hemi engine, coupled with fuel injection and a six-speed manual transmission. The meticulous engine build, featuring a 392 cubic inch stroked Hemi with Eagle heads, Wisco Pistons, and a custom Comp Cam, showcases the team's dedication to creating a high-performance masterpiece. Despite setbacks with parts availability, the team perseveres, focusing on rebuilding suspension and steering components to enhance the truck's handling.

As the clock ticks, the team, including Fryberger and Birdsong, races against time to complete the build within a week. Challenges with the front accessory drive installation and wiring for the Holly Terminator X EFI controller add a layer of complexity to the project. From the installation of the Holly High ram intake and throttle body to the meticulous plug replacement and clutch upgrade, every detail is meticulously executed to ensure optimal performance. The tension reaches a peak as the team successfully navigates the nerve-wracking process of lowering the engine and transmission into the truck, marking a significant milestone in the Mobark Muscle Truck's epic transformation.
