EMD 567, 645 & 710 2 stroke
EMD 245? 4 stroke
Detroit Diesel 53,71,92,110,149 all 2 stroke.
AIUI the Detroit and EMD 2 strokes were the product of a research program
conducted by GM in the 30s.
GMC also produced the Toroflow engine for buses (& trucks?) in the 50s. Some of
the Ansett Tour buses were fitted with them. AFAIK this was a 4 stroke motor.
