The KB kits are pretty good so I would recommend getting one, installing it before adding too much more. IMO, you don't want to go too far with the stock rods. My guess is it will make more than enough power on its own. I haven't seen where headers on the 4.6L engines return the same improvements that they do on pushrod engines. I don't think there is enough room in the engine bay to design them to be as efficient. Plus the stock manifolds aren't too shabby.

Thanks for the info! It does sound like the Kenne Bell would be the way to go. Are there any other mods you might reccomend for duribility (I do tend to put my foot into it a lot)? Also is it worth it to install headers? I read that an 8psi Kenne Bell kit made 500HP on a stock mustang with stock exhaust and mainifolds..

They put allot of effort and thought into their designs and supply everything that is needed. They also provide excellent support. I would also recommend them over Saleen. As for centrifugals, they make good power but it is in a narrow rpm range of around 5k-6k rpm. Kenne Bell uses a twin screw that will let you know it is there all the way from just off idle to the red line. It will turn your 4.6L into more of a torque monster than a strong running N/A 460 c.i. engine. My 5.0L with a Kenne Bell makes 460 ft-lbs of torque at the rear wheels at 2,500 rpm. The KB kits for the newer GT's should be awesome when combined with the variable valve timing on the new motors. My guess is you will make the same horsepower and torque that an 03/04 Cobra makes after a few cheap mods. The one weakness with the GT's V-8 is the powder formed rods. They do fine up to around 425-450 rwhp but after that they can bend.

Originally I got on the list for a 07 Shelby GT500 (number 19) but just recently learned from my dealer and several other local dealers that Ford has decided to limit production and they will only be receiving between 2 to 4 for 2007. Because of this I have decided to explore the option of getting a 06 or possibly 07 GT/CS convertible and having the dealer install a supercharger.
One dealer I spoke to said they mostly install Saleen superchargers (which does have a nice clean design) and are good for 400 - 435HP depending on other modifications. Another dealer I spoke to said they recommend Kenne Bell superchargers and they are far superior to the Saleens and provide more power for the dollar (over 400 rwhp as opposed to Saleens 400 hp at the crank). I am always looking to get the best bang for my buck but I also want a supercharger that is the most reliable and would work fine for daily driving. Does anyone know of any issues with either of these superchargers or have any better recommendations? I did briefly look at the Vortechs and Paxtons but from what I have read regarding Superchargers and Turbos I think I would prefer the feel of a Roots style to that of a centrifuge (More of the feel of a big block motor and no RPM dependant lag).
