I've had 2 V-10 trucks, and liked them both. This last one has the 3 valve system (2005 F-250 SD 4x4) and pulls very well. As mentioned in another thread, I put a K&N air system, Gibson Exhaust and Banks power chip. I can pull my 25ft Titanium 5er on most roads with the cruise control engaged, and only use the "tow mode" in hilly areas.
Several things add to the V-10's desirability, they are overhead cam engines, so they can safely rev higher than push-rod engines, they have aluminum heads, so the engine total weight is lower (about 890 pounds lighter than Ford's big diesel), and they do not need tubro-charging and associated inter-cooling to get the torque numbers up. So far gasoline is cheaper than diesel, but that can change. There is a heck of a lot more room under the hood of my truck than my friend's with the diesel. Heaven help him if he has to change an alternator. I just wish the transmission was as beefy as the engine.
Oh, I do miss the V-8 sound, even with the Gibson exhaust this thing sounds like a pregnant bumble bee stuck to a rock singers microphone.
Finally, anyone else find back-up info for Ford cutting the V-10 out for 2011?
