Although this video is not a Chevrolet 40 to 60 series truck, the engine powering this 1971 GMC TDH-3301 transit bus is the same Toro-Flow DH478 diesel V-6 as used in those trucks. Due to the poor nature of the beast, these were usually replaced by other engines, including the Detroit Diesel 6V53.
This leads me to ask: does anyone here have any pictures of any 1967-72 CG/MG50s or CG/MG60s with the DH478 engine?
