| I have a 3176 in a 1993 truck set at 350HP. I thought the 1993 was great until I bought a 1996 with a 475HP 12.7L Detroit. But the only difference the extra 125HP makes on a 30 mile trip with an 80,000 lb load is about 20 seconds. If you are not going to be pulling doubles or a tri-ax with 100,000 lbs, then a 3176 will work fine. As far a reliability, I haven't had as good of luck with mine. It started getting fuel into the oil a few years ago, but the Cat shop couldn't find the source of the leak, so I just changed the oil more often. Then two years ago I found that fuel was getting into the coolant as well, so now we are just using it as a backup truck until a cylinder liner o-ring fails from the diesel contaminated coolant. | |
