You do realize that is a spyder injected intake system correct? You will best be safe to do another intake manifold with a wilson/90 degree elbow or a ramjet setup.
These are what you will need to look into.

Or make your own direct port fuel injection with a new intake manifold , fuel injection system etc etc
Your stock fuel system WILL Not support the 500 hp . You will not be able to get the stock sypder injection system to handle it either. You will need to look at other means of fuel deliver to the cylinders.
