Having a new cat built over the next few months. Rather than rigging it with 400r's as I originally planned I'm tempted to sit and wait a bit. Is there any gossip or rumors floating around of higher hp engines based on the new 4.6L V8's? I'd wait a year if indeed something bigger is on the horizon rather than buying the current 2.6L 400R's.

Anybody heard anything related to this?

Thanks,
David
