I bought the 6.2l two weeks ago and love it. Given the history of the automotive industry I'm sure it's only a matter of time before improvements are made on this engine. But, and it's a big but, I don't see that happening for a few years. Ford is going to want to recoup all the R&D and tooling costs for the 6.2 before they start offering other choices. I couldn't be happier with this engine for my purposes, it was a huge leap forward from the 5.4L.
