Hi all, I just bought a brand new left over f-250 fx4,crew cab and it has the 5.4 engine. Is this engine going to be adaquate for my truck if I do not plan on doing a lot of super heavy hauling? Also how hard would it be to swap out the engine maybe down the road and put in a V10? And 1 more question. I have be trying to find a cold air intake system for my truck/engine combination and have had no luck. Everything seems to be for the V10 or the powerstroke. But is the air intake the same for the 5.4 and V10 on the 2008 f250? If it is , I was just going to order one for a V10 and use it on my truck. Can I do this? Thanks for any help!
