I have comp xe270's which is what you might call a stage 2 cam. If I went all the way up to the 274 or 278 then things would be a little taller yet on the hp line but not enough to justify their radical idle for me. I have Fox lake stage 2 ported heads too. I know there's at least 10-15hp left on the table from the adapter plates messing up the air flow path and fuel mixing, probably another 10-15 in getting the tune just right after that. Longtubes have shown themselves to be worth 20-30rwhp in this application but it's currently very expensive to put longtubes in as they have to be custom. I'll be embarking on a trip to solve that problem pretty soon. I know you can make 340-360rwhp and similar tq with a properly set up engine and cams on the hot side. I'm hoping to end up with 315-325hp and 340-350tq . I don't see much problem hitting that mark with the upcoming mods.FWIW...if you're going to do this make sure you have an aftermarket upper plenum and 75mm tb.    thats a good bit of hp/tq there for just a NA motor right? an all that fits under ur stock hood, iam guessing ur using the pi intake. damn that all really sounds to good to be true. hows the power band on it, i know its not really a high reving engine but i know its got to pull like a mofo for awhile. an just to satisfy my curiosity is it possible to put some kinda forced induction on that type of motor and keep it all under at least a 3in cowl hood? i would love to know as much as possible on all of this 5.4 stuff, this is tooo freakin cool man.</blockquote>
