If we assume a 15% drivetrain loss, here are estimated crank numbers:

Average HP: 227.04 x 1.18 = 267.1 HP
Average TQ: 276.316 x 1.18 = 325.1 ft/lbs

If you're asking why Ford underrates the numbers, I'm guessing because the advertised numbers are minimums guaranteed, while manufacturing tolerances and tune variances allow certain (most) cars to be above that.

It goes like this,
If you buy an ST, and it dyno's above the numbers, you think "Thanks Ford, you made my ST awesome!"
If you buy an ST, and it dyno's below the numbers, you think "Screw you Ford, you lied to me!"
So when Ford underrates the numbers, you get more happy customers.
