This video dives deep into the story of the GMC 478 cubic inch V6, a forgotten torque monster that defied conventional engine design. Built exclusively for heavy-duty trucks, buses, and workhorses, the GMC V6 family proved that displacement beats RPM. With enormous cylinders, a 60-degree V6 layout, and gear-driven camshaft, the 478 V6 delivered massive low-end torque, legendary durability, and unmatched longevity.
The GMC 478 V6 was never designed to impress on paper or dominate racetracks. It was built to start every morning, pull impossible loads, and keep America’s infrastructure moving. It represents a philosophy that valued endurance over efficiency, simplicity over complexity, and function over form.
