Yes.......the engine will fit. I would suggest swapping both the engine and transmission because the SC engine has a HD transmission to take the extra power. You also need the Engine control module (computer) the hard part of these swaps is the electronics, getting the Engine module wired into the 03 body module and having all the gages etc work.
