These engines were manufactured by General Motors' Detroit Detroit Diesel Engine Divisionin Detroit, Mich., USA. Designed in the late 1930s, the GM Detroit Diesel 71 series was built in one, two, three, four, and six cylinder inline models. The 6-71 obviously was the six cylinder version.

I suspect "6004 Special" refers to a the configuration needed for it to fit in the Valentine, e.g. different oil pan, exhaust manifolds, engine mountings etc.
