A stock 2003/04 cobra is rated at 390HP. This rating is also very conservative, with some making upward of 430HP totally stock.
The Cobra coupe weighs 3665lbs. An '05 GT coupe weighs 3483 lbs.
Both come stock with 3.55 gears (with the '05 GT being a 5 speed), but the Terminator is IRS vs the GT's solid axle.
Even with a slight weight advantage, you would have to have gears and a seriously built motor to even stand a chance N/A.
