5.4 swap

So I finally got lightning engine, I also got a Kenne Bell supercharger. Now what mods do I need to do to drop that beast in my 04 GT?

They make headers for a 5.4 swap into a mustang, either that or could just use the manifolds off the lightning and rig the exhaust to match up with them

Exhaust for the lightning atleast long tubes is custom ur looking at a stack atleast for lts. Either that or try to find the lts ford racing made for the 4.6 which fit perfectly....however that is a rare find the lts from ford racing

You could probably get away with a 4 inch hood and 2 inch spacers in the kmember

The navigator 5.4 is a dohc and I highly doubt it will fit in-between the strut towers without alot of surgery
