Trickflow 4.6 in hotrod

I'm surprised no one has posted about this yet. There is an article in the June 2010 issue of HotRod about a 4.6 build up using the trickflow heads. The combination is simple: junkyard NPI block, trick flow heads/cams, victor jr. intake, demon carb and long tubes are the basic parts. The whole thing made 454 hp @ 6400 and 390 ft*lbs at 5200. That is just amazing from an N/A 4.6. And it is a relatively simple combination too. They show the total price being $5,600, but I'm thinking the stock rods won't be happy for too long above 6k.
If you want to learn more about the design process and considerations of the trickflow heads, I highly recommend reading the article. They mentioned that the layout trickflow started with was based on the 2.3 ford engine, which I am slightly partial to.

Yes, the numbers are at the crank.

I don't see what there is to be skeptical of. Sure, you won't be making that much power after installing this combo in your mustang, due to drivetrain losses, the power steering and any other accessories they wern't running on the dyno.

This is a high reving combination, designed to make power from 5000 to 7000 rpm. They took out the restrictions, such as the OEM cylinder heads, fuel injection intake and the short tube headers. This is a pure example of a head/cam/intake combo making power. I am not sure if it would be much fun on the street though.

As for making this a fuel injected combination, I would imagine you could come close with something like the trickflow intake(but don't use a plain PI intake!). For most people, it is hard to beat the PI intake because their operating range only goes to about 6000 (due to PI heads and cams), but with the trickflow head/cams, the bigger intake will suit you nicely.
