The 8.2 Detroit Diesel was used in the Canadian variant of the M35 2-1/2 ton 6x6.

Some people love them, others hate them (both trucks and engines). I once had a MSE Op (driver) comment that she preferred the old M135 with the GMC 302 motor. Also, my M135 (light) would outrun the later (loaded) model on the highway. It was always fun to see their faces as they were passed by the older truck that their "new, improved" truck had replaced.
