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.</blockquote>
