Bought a 4.7 for my Dodge. After replacing everything but the intake, intake isn't available anywhere, the engine smoked like crazy on start up. Put in a claim right then. After not even five minutes of run time. Factory called back and told me to run it. Well, 5000 miles later it blew. Now my three thousand dollar engine is worth a five hundred dollar core. And "customer service" refuses to do anything about it. Lesson learned.
