Well I know they'll make the car sound awesome, but I'm not sure if they'll make the power at too high of an rpm for a street car. According to their website the stage 3 cams make power between 2500-7000+ rpms, but I suspect the bulk of the power will be at the higher end of that scale.
I really think the best thing would be to [urlhttp://www.crower.com/misc/contact.shtml]contact[/url] Crower and see what they recommend. Of course if you're getting them cheap enough and are planning on going with an even more radical setup then maybe it's worth the plunge?
These aren't '05s but at least you can get an idea of what the car sounds like with stage 3 cams.
