Really increase the power of my car yet still keep it reliable. I do not want to install mods that are going to hurt. I want to stay naturally aspirated. Want to keep my car as a sleeper. No obvious work done. I'd like to be able to hold my own against a mustang cobra, the stock 390bhp one that anyone can just buy for $30k.

Couldn't of said it better my self, nice. I would go for the LT4 conversion.

I've been looking at the same thing. I was almost convinced to do the LT4. I think I'm going with a port/polish/valve job on my stock heads and a custom ground cam to match. The $$ add up quick though. It blossomed into throttle body, injectors, headers, rockers, timing chain, blah blah blah.
