Good engine. The overhead needs run on them religiously at 100,000 it probably needs ran again fairly soon. I have a 400 in my 9670 and it has the low flow coolant system, I have no complaints with it but my cummins mechanic doesn't have much good to say about that system. I'm sure yours is the same being a 91.
400 big cam cummins??
