I am no GM expert but I have seen a few. One on a navy ship I was on was a 6-71 on an emergency generator, ran at 1200, rpm and was rated at 60kw if I remember. Sometimes it was run along with the regular ships service generators and for months at a time. Some 6-71s I ran in boats in Guantanamo Bay would only run up to maybe 1700 or 1800 rpm. They weren't new at the time, (1969). It depended on the condition and the load. Some of the newer ones in landing craft would run up to 2000. I went to engineman school at Great Lakes after bootcamp and one of the instructors told of being at a GM school and one of those GM instructors told of GM hotroding some 6-71s for high speed power boat ocean racing and they ran those up to 3500. not sure I would have wanted to be too near one of those.
