Thanks for all the replies. I wasn't sure if the engine rpms would get too high going down a steep descent keeping in a low gear. All of the late model gassers I have been looking at had Ford chassis with the V-10. What is redline on these motors ?
There is no redline for these motors. The computer will not let you hurt that motor. I've seen 5000 plus RPM on our rig when going down a very steep grade but the V10 was holding speed just fine. I use a combination of Cruise Control and Tow/Haul.
Well, technically they do have a redline. You just would never reach it with the stock programming. I have raised my shift points to 5200 RPM and the fuel cut to 5400. So far so good at 394,000 miles except I can now hear some occasional timing chain slap (worn guides I'm sure). Would the guides have lasted longer without so much time spent north of 5,000 RPM? I don't know, but doing a timing chain job every 400,000 isn't exactly going to break the bank, and I sure like the extra power on tap.
