what's the word

It is my understanding that the northstar for the sts and xlr will shrink from 4.6 to 4.4 but have a blower attached with enough boost to get 440 hp.
Any owners of xlr"s on this site? Need input (good and bad). With the increase of hp in the new sts-v comming out next year with over 400hp , is there any talk of more hp for the xlr? How are the 2004"s and 2005s handling, performance etc. Any info would be appreciated.
Thanks
Gary
