It's a C3500HD rollback I picked up at an auction for a good price I think. I drove it around the parking lot and it seems to run fine except the idle is a bit high around 1100 rpm. How much life can you expect out of these engines? And I had a '94 Suburban with 180K for a few years that ran great. What is the difference between the two engine wise?
