The **6-71** blower was originally designed for a **6-cylinder, 71 cubic inch-per-cylinder** Detroit Diesel engine—making it roughly **426 cubic inches** total displacement. These Roots-type superchargers weren’t built for performance at first, but hot rodders quickly saw their potential. Their robust construction and ability to move serious air made them ideal for high-horsepower builds, especially in **drag racing** where big boost = big power.

As you said, **4-71** and **6-71** were the first to get repurposed, but soon the aftermarket exploded with **8-71**, **10-71**, **14-71**, and even larger blowers—purely built for racing applications. While GMC never made an inline 14-71 Diesel, the naming stuck as a convenient way to size these beasts.

Lesser-known roots blowers like the **8V-71** and **4-53** have also seen some hot rod use, but they're heavier and less efficient compared to the refined aftermarket options today.
