390 at the crank according to Ford. It's really around 410-415 at the crank.

RE: 03 cobra hp

The blower is set at 8 lbs stock.

Pre-mods my totally stock '03 ran 365 at the rear wheels, i.e. one would expect that to equate to 429 at the flywheel. Post mods but pre-"final tuning" she hit 585 at the rear wheels on 91 pump gas (est. 688 at the flywheel). These cars are incredible...
