These things were too weak for these big trucks fresh out of the factory, even more so when you start putting bigger tires & more weight on them.
Even if I didn't have three 4.6 trucks, I couldn't agree. Those specs give the Discovery 2 a better power to weight ratio than a contemporary 4.7L LC100, and people go crazy for those. This post also links to a video of a Discovery 2 with several hundred thousand miles on it, loaded to the gills, clawing through deep snow on 39-40" tires.
We must just have very different wheeling experiences. I started wheeling around 2009, so I'm not holding an engine that went into production in 1996 to 2023 standards. The 90s Ford, Chevrolet, and Dodge 4x4s that were cheap enough to wheel made similar or less power out of 5.0-5.9 V8s and weighed 500-1000lbs more than a D2. The 4.6 has weaknesses like a lot of engines, but it's not really under powered for it's era.
I know I am jinxing myself but I have been very happy with 4.6 LRs, for what they are. Until the last few years, most of mine were stock too. Sorry you had a bad experience.
