supercharging a 2000 navigator

i purchased a novi 2000 paxon kit and bought all the upgraded fuel support 42#injectors and a 255lph walbro pump about a year ago and was going to install this on a f150 only to find out that the 2 kits were different!!! well i still have it and now that ive bought this navigator i wana go ahead and use it on this navigator.
?
?
what kinda HP will the 32 valve intech engine support?
what kinda boost can shove down and still keep my engine in good running order?
ive got a set of BBK shorty headers that would fit my f150 and my expedition, will they fit the naviagot 32 valve engine?
is there a different intake/plenum so i can add more hp ?
anyone know where i can get a blower cams that can support a good mix of low end and top end power?

My advice to you would be to check out a mustang forum. Lots of guys are putting the 32V 5.4 into foxbody mustangs as well as the later cobras. The bottom end will support big HP #'s and that's why these engines are so desireable. Make sure you run nothing but premium fuel in it, even while its not boosted that's important.

There is a ridiculous amount of info on the cams that can be had for those heads, but it will require changing valve springs and valves so the price tag climbs fairly quick. (not that the cams aren't expensive on their own) If you wanna run any boost ARP head studs are a good idea.

Check out some mustang forums, not saying there isn't good info here but mustangs are more of a performance driven community and it seems like you may want to get all that info.

There's also a seperate forum here for these 4.6 and 5.4 modular engines.

The headers will not interchange due to different port shape and size as well as the bolt patterns are different.
