84CopperGT

So I am looking at the Ford Racing Boss 351W block right now. I am thinking 4.125 and a 3.750 stroke with 9:1 compression for a single turbo setup. Not looking for straight line only power. I only want about 650-750 to the wheels. My main question is roughly what CI it would have (thinking just over 400) and how much can I make on the engine before adding the turbo (thinking just over 500 conservatively).
