When EXACTLY did the 3 Valve 5.4L come out?
The '04 in my signature was built in January of 2004. I've heard a bunch of BS about whether it's a 2v or 3v. Owners manual says 3v, but I got called out on it earlier, so I wanted to start this thread to settle it once and for all. Any dead give-aways as to what engine it is? I'm really not trusting the owners guide right now.
