So out of all of the 2v,3v and 4vs 4.6 and 5.4 which is the easiest to make power

They can all make power it just depends on how it's done and how much you want.

There's no replacement for either displacement or airflow so a 5.4L 4v will be able to make more than a 4.6 4v if the rest of the package is carefully selected.

"How much does each cost to build?"

I’m no modular expert but I don’t think there’s an abundance of power making parts for any of them other than forced induction. They don’t have the aftermarket cylinder head options like the push rod 302. Since forced induction is about the only option I’d probably choose whichever had the best aftermarket in that realm. If you go 2v you’ll be starting with the lowest power rating of course, so there’s that much more ground to cover.

Abundance? No. But there are options that greatly improve the power production potential of a 2v. Unfortunately every inch you go down that road leads to a more radical package overall and the cost is pretty heart thumping for the returns you get. With the right bottom end, intake, exhaust and cam package a 5.4 4v can pretty easily put down a bit over 400rwhp NA with a torque curve that's flyover state flat. Of course you could toss a single turbo on it and roll out 800rwhp pretty easily too. Pre-coyote Ford stuff is pretty badly handicapped by todays standards until you get all the way back to pushrod motors.
