LT1 350/383 into 90 IROC 305 TBI

What I want is an engine that will get me between 400-450hp supercharged, possible with nitrous. There are alot of after-market parts for LT1's that I found that give you speed enhancements. Is what I want realistic and does anyone have any recogmendations for me? I want to spend maybe, between $4,500-$6,500 on an engine from start to finish.

You don't need a supercharger or nitrous to get 450 hp from an lt1. If you are refering to crank hp then it is actually quite simple. Port the heads and change the cam and valvetrain. THen put a good exhaust on it and have the pcm reflashed. I havent had my car dynoed yet but it should put down between 350-375hp at the rear wheels.
