Just decided to pull the 460 engine

So after all the threads and me wanting over 400 hp I am really considering just pulling the rest of the engine and going from scratch, I would like to hear some feed back on this and were I should start with up grades to the crank and pistons and anything else I need to look at I would really like to get to 500 HP

Just do a .030 x 4.50 and it will almost idle at that hp.
