Thanks for the response. I wasn't very clear on the prostreet thing. Over a few years my craze for racing had slowly evolved m y car into a strip only car. But now I miss driving it around. I decided to go with an LS so I could drive it as a fun daily driver and slowly add some power to it and still keep it streetable. But I know once I get to driving it around again I'll feel the need for speed that's why I want to be ready for nitrous cause it probably won't be long before I put a system on it.
