Engine torque
After the engine in our '09 V10 6.8L F250 'sploded 3 days ago, we ended up with a new-to-us replacement '12 GMC 2500HD that we were able to find on very short notice.
The V10 6.8L was rated 362HP with 457 ft-lbs torque. The 6.0 V8 in the GMC is almost identical HP at 360 but the torque is 380 ft-lbs. Both trucks have a 4.10 rear end.
Am wondering if the torque difference is going to be noticeable and if performance will be down in the mountains? We've towed our 7K lb TT around 7 western states and last week up to Jasper Alberta. Been on many steep and/or long inclines and the F250 never left me wanting more power/torque. Am also wondering if I'll end up pushing the GMC engine harder and causing more wear & tear?
The V10 in the F250 started making a very faint ticking/knocking sound at first. Then within less than a couple of miles the knocking got louder and louder to the point it barely moved and then died. Just got around around a corner off the highway and across railroad tracks in time. No power steering or brakes either of course. The mechanic at the shop it got towed to pronounced the engine terminal due to serious bottom end damage like broken rod cap or major broken something. They and us looked everywhere for a new or used V10 engine but they aren't very common and only found 2 a very long ways away and shipping, labor + engine cost would have been as much as the truck was worth if not more. We basically gave the F250 to the guy who sold us the GMC for nothing on trade-in value. :(
No idea what led to the demise of the V10. Changed the oil & filter yearly, had about 140K miles on it and it always ran great. The oil pressure was good right up to the end (unless that gauge was defective). We used it mainly for towing and it mostly sat in the driveway through the winter. Well under the GCWR too. There are some steep and long inclines in the Rockies and the engine was working pretty hard at times.
Maybe I just need to slow down and run with the semis over on the shoulder up long & steep grades, lol! At least we have a new truck and can keep on campin'. :)
