Is the swap to a 5.4 L really worth the trouble??
Yeah like I know the 5.4L engine in my F150 is a 3v but I wouldn't use that engine, I love that truck and yeah a 5.4 L 4v would be crazyA 5.4 2v would add lots of torque to the low end but not much more hp. A 4v 5.4 would be a bat out of hell!! but i dont think they even made 5.4 4v's with out a supercharger.
I'd be interested in reading that write up, I'm always up for learning something newThe 5.4 just has a taller deck height. And a little wider. Pistons are same heads cams sensors computer. Everything is the same. Makes for a easy swap. I havr the write up on a 5.4 build if anybody is interested
