Can they build a 400hp 4.6
 

Is there any company that builds the 4.6 motor that can come close to 400hp, cam,intake,heads,etc,, not supercharged and nitrous injected, built

Sean Hyland has. I saw one 4.6L motor make 425 hp NA. Of course they were going to put a blower on it, so it was only running 8.5:1 compression, so it could of been even more powerful.

The FR460 made 385 hp out of a NA 4.6.

IF u want 400hp out of a 4.6 best place is sean hyland such as snake driver metioned. All of the fast 4.6's i have seen or read about all came from his shop.
