I've seen a few of your posts on the board and I am concerned about your future here. First, PLEASE use the spell checker - some of your sentences are unreadable. Second, this post has the sound of a troll (someone who enters a website to do nothing but cause trouble) which is a reputation you don't want to foster.
Now as to the specifics of your question, you cannot build a 383 IROC Z28 (if in fact you actually have a car like that) without a source of quite a bit of money. Car building is an expensive hobby and there is no cheap way of doing what you want to do. Another thing that flags this post as a possible troll message is your total lack of detail concerning a relatively sophisticated car project. We have had many, many young people come on here claiming to have Hemi Cudas, Lamborghini's, etc, etc., when it was painfully clear they probably didn't even have a 1/25th scale model of the car.
Just some thoughts that will hopefully help you benefit from your time here.
