For anyone that is interested - Nelson Racing Engines just posted what I feel is a great deal for a complete drop-in Twin Turbo LS3 engine. It would definitely make the new Camaro scream. After seeing all the post of power adders I figured to post this for anyone looking for a big step up in power. I love power adders, but am always afraid of the bottom end coming unglued. This is a completely new engine build with the best parts.
I am not affiliated with Tom Nelson, but have one of his engines in my Firebird and I can't say enough about the quality and support I received. His stuff is absolutely top notch. So, if you a want some insane streetable power for your new Camaro you might want to take a look.

His phone number is 818-998-5593, but be forewarned you will probably have to call a bunch of times before he gets back to you. I used to always try to call and he was never in his office, always out in their shop or on the dyno...
