That's one bad ass car. It was an interesting read on the development by Huffaker Engineering. They started with a crate Ford GT engine and tore it completely down and turned it into a NA monster. I can't figure why you would do it that way unless Ford gave the the engine package. I guess it had the dry sump, 5.4 aluminum block, and the good heads. After that they had to redo pistons, rods, cams, intake, and who knows what all to make it what it is.
