Let me suggest you enjoy the car a little as is. No reason you can't take the car to the track as is and get some time in the seat and decide if you really want to do this. Sound like you want more than race with it which will effect how you build it. I don't know if you have put pen to paper but your going to spend well north of $25,000.00 to put a 572 in there and support it and that's doing the work yourself.
