In my opinion, coyote swap is the way to go. There has been plenty of guys do the swap and from what it looks like, is its not that difficult. There is even an aftermarket following making parts for the swaps now. I don't want to offend anyone, but I would absolutely NEVER build the 4.6 2v in my car. I know there is a niche crowd that likes make big power from the unassuming 4.6 2v, but there are much more economical ways to make power. If youre content with 400hp, throw a vortech on it and call it a day. If youre looking for big power, the coyote swap is the way to go. Drop it in and you have 400hp n/a from a factory-reliable new motor. If you get bored with it, slap a blower on it and have 600+ wheel horsepower.
