Ford Racing placed an ad in this weeks National Dragster, I though its pretty cool that they show support for not only the new cars, but the old ones also.
kdanner, I don't know why your having issues locating parts. PM and I will locate all parts that you need. They are available from Ford Racing. I assume when your talking about a zip tube, you mean the air intake. There is no air intake on the 5.0 N/A like they have on the supercharged combo. The part number for the COBRA JET 5.0L 4V INTAKE MANIFOLD M-9424-M50CJ*, and its the same as the as factory cars.
Jim, I assure you the parts will be around for a long time. You can build a clone CJ, 5.0 N/A or 4.6 for the same money you would spend I any similar older combo. You can pick up 2010 Mustang fairly cheap these days.
