Simply put, Flash, your 323 HP is rated at the flywheel - engine only, no load at all. The dyno readings everyone looks for are at the wheels - which is under load. Starting at the engine, there are lots of mechanical elements (transmission, drive shaft, rear end, etc. - not to mention car weight) that rob power, so by the time it gets to the rear wheels(which is what really counts) you've probably lost as much as 20% (it varies).
