i was doing some research online and i found this article from hot rod magazine and they did a build up on a ford 4.6L and thought i would share it for the guys that thing these motors have no power

Ford 4.6 Engine - Junkyard Jewel Ford 4.6l 2v - Engine Build Up - Hot Rod Magazine

 

The new hot rod magazine shows a new set of heads for the 4.6l they flow so much better than even there ported PI heads. I think they said 453 hp from the same engine by switching to the new style heads and cam. I think trick flow made them.

Cant wait to see someone bolt these puppies to a 5.4l truck engine and see what kind of numbers it can pull bellow 5200 rpm.

I know the heads in the new mag are designed to address the severe flow issue with the stock 2v heads.
