This is an antiquated argument that really needs to be put to bed. The current trucks line up looks like this: Ford 6.7L: 400HP... 800ft/lb GM 6.6L: 397HP... 765ft/lb Dodge 6.7L: 350HP... 650ft/lb Ford 3.5L: 365HP... 420ft/lb Dodge 5.7L: 390HP... 407ft/lb Toyota 5.7L: 381HP... 401ft/lb Nissan 5.6L: 317HP... 385ft/lb Ford 5.0L: 360HP... 380ft/lb GM 6.0L: 322HP... 380ft/lb GM 5.3L: 315HP... 335ft/lb Dodge 5.9L: 245HP... 335ft/lb (2002) Dodge 4.7L: 310HP... 330ft/lb Chevy 5.7L: 255HP... 330ft/lb (1997) Toyota 4.6L: 310HP... 327ft/lb GM 4.8L: 302HP... 305ft/lb Ford 3.7L: 300HP... 275ft/lb If the argument is that you need displacement to pull a trailer, then you are dead wrong. Technology can AND will replacement displacement. You can see Dodge's and GM's largest engines (5.9L and 5.7L) have been WELL replaced with more modern designs. You will also notice that the largest engine (GM's 6.0L) is eclipsed by 5 engines with less displacement. On the diesel side of things, the larger engine does not necessarily make more power/torque. And before you say something about the turbo engine not being good due to turbo lag... remember, the big, bad diesels have all been running turbo for a long time... you won't see a normally aspirated engine pulling a 50K pound trailer down the highway As emission and mileage requirements go up, you will see all the manufacturers finally put to rest the idea of "no replacement for displacement" and join what foreign car makers have known for a long time... technology and boost are the ways to go. With Ford dtepping up their product line and making an engine like the EB for a truck, the other makers will now have to step up. Once people start seeing the joy of getting 20+mpg out of their work trucks and the cost savings associated, fleets will start changing over to them and if GM and Dodge don't keep up, they will get left behind. Disclaimer: I ma not a Ford lover. Quite the opposite, I grew up in a GM family... but now with the new engines from Ford, I would NEVER buy one of GM's antique-like 5.3/4.8L engines.
