This video from Cleetus McFarland documents the engine swap of a big-block Chevy engine into Zach's wagon and the giveaway of two F-150 trucks to contest winners. The video also features a product sponsorship segment for Carly, a connected car diagnostic tool.
Zach's build involved installing a big-block 632 cubic inch Chevy engine into his wagon. During the process, they initially installed the cooling fans backward, causing overheating. After correcting this, they completed the installation and Zach did a burnout at the end, showcasing the power of the new engine. The burnout resulted in some debris hitting nearby vehicles. There was also a brief moment where the engine initially wouldn't start due to a timing issue, but this was quickly resolved.
