The GMC 6-71 diesel engine with corresponding 6-71 blower was frequently used as a truck engine, marine engine, or generator power source or a pump power source. These units are 7.0 Liters, 426 cubic inches, and rated at 190 HP. The case and rotor length for the 6-71 blower is 15.0 inches. The 6-71 was/is adapted for use on hot rod engines, Bonneville type cars, race cars, etc. When these units were no longer adequate for air flow, race car blower companies started making longer blower cases and rotors with their own castings, maintaining the nomenclature such as 10-71, 12-71, 14-71, and even 16-71.
