Power limits for LA small blocks?

I want to keep the interior untouched and


I want to keep the car in full street trim. I dont want to do anything to the interior and possibly only a glass hood. I also would like to be able to run it with a streetable gear. I am sure some guy is out there running 11s with a full interior and 3:xx gears but that is not easy.
I was talking about full interior and street gears (3.23 - 3.55). Quit listening to your buddies that say they have a 400 hp 350 in their Camaro and run 15's LOL.....
