Is a 2003 F 150 5.4 engine interchangeable with a 2005?
My engine on my 2005 needs to be replaced. I found an 03. Just trying to
figure out if I can use it or not.
The 2003 engine would have 2 valves per cylinder but the 2005 has 3 valves per cylinder. I would recommend going with a correct engine. Check out the crate engines that Ford sells.
