I have owned 6.0L Powersmokes since 03 when they came out. They had problems, but when set up properly and "bullet proofed", they are a great engine. (I am rebuilding one now). The new 6.7L, since 2011, is an excellent engine. Ford really has it figured out now.JC
It's all about a combination of personal experience and perception.That does surprise me about your ESCALADE. That engine has been around forever in some form but I guess whenever revisions are made, someone must have goofed up something in the process.
