I've been advised that if I wasn't to up the HP of my SHO that I would need to replace the intake manifold for greater air flow and replace the fuel injectors for greater fuel flow. Oh and to get a bigger wallet to support the extra cash outflow.

How do car manufacturer make 400 500 600 700 HP just by a different key fob?
The SHO has variable valve time, which means the cam lift can be changed via computer only. Fuel mapping is changed, cam timing changed, etc... I have a 225 on a ranger z119c. I flashed it to 300 and went from a 25 T1 yamaha prop at 5850 RPM and 72 mph to a 26 T2 at 6050 RPM at 78 mph loaded. I've had it at 80.2 mph by myself with a half tank of gas, but it will run 76 to 78 loaded with two people full tackle and full fuel.
From a manufacturing standpoint, making all form 200 to 300 HP identical and controlling with software is the least inexpensive way to go. And you need less replacement parts in inventory.
