Can't fault a guy for searching, even if he digs up an old thread.
While I'm here...
I had a '76 280Z with a SBC... it was pretty quick, so I figured "Demon Z" was an appropriate plate for it. I later used it on my '05 350Z and now my 370Z too, continuing the Z car tradition. And since I needed a user name for a Z forum when I got the 350, it seemed like the obvious choice.
