Never said it made 400whp stock I said it made 385whp stock.

If you had bothered to search even slightly you'd find that the majority of stock 03-04 Cobras rated somewhere between 370-390 whp.

With a 15% drivetrain loss that equates to about 425 crank on the bottom end of the scale.

Since they were rated at 390 crank at the factory, that would make them underrated would it not?
