I still think Ford should offer a 5.0 version. Between the harcore desert runners and the V8 guys I think it would create more sales.
These threads are so entertaining though, I don't know what I would do if they went away.
Raptors are already somewhat difficult to find even with a 3.5L as the only choice. Somehow I think your logic is flawed.
I'm also pretty sure Ford is happy with the sales of the Raptor. If they weren't they would have introduced a v8 or whatever they felt like they needed to make based on *gasp* market research, already.
