my dad passed away a few weeks ago and one of the things he left me was his 2009 f-150 stx 2wheel drive ,it only has 8000 miles on it ,i believe it is a 4.6 ,but i cant tell if it is the three valve or two valve one ,,how can i tell
sorry for your loss as well. to answer your question, it is the 3-valve. in the new models, 09+ the 4.6L was given the 3valve treatment, mainly to ramp up sales before they pushed out the 3 new engines: 3.5 boost, 5.0, and 6.2. take great care of that truck as if your dad was the one still owning it.
sorry for your loss man. but on the upside, you now have something that you can use and continually remind yourself of him!
Sorry about your dad. Your truck is a 3v and I'd keep it as a weekend cruiser and leave it bone stock, or with whatever mods your dad did to it.
