Did you have an luck yet? GMC has quite a few diesel V8s. They have an 8.2 L, a 6.5, 8v53, 8v71 and 8v92 off the top of my head. Photos would help.
here is an 871 http://www.industrialdiesel.net/industrial%20engines/8v71_rebuilt/8v71_rebuilt.htm
here is an 8v92 http://www.industrialdiesel.net/industrial%20engines/8v92_rebuilt/8v92_rebuilt.htm

I bet it is the 8.2L
