UPDATE:
Looks like the PDF below was slightly off from the official final figures.
GM has just released official published final HP/TQ figures of 460 hp / 465 lb-ft.

PDF documents (images below) about the C7 Corvette have turned up on GM's
media site and if the specs on the the C7 coupe sheet is final (which they appear to be since they no longer have 'est.' [estimated] next to the numbers), then we now know that the 2014 Corvette has official HP and torque figures of
455 HP and
460 LB-FT.
Compare these final figures to the specs for the C7 Convertible, which still has the estimated (est.) figures on its sheet.
If you remember, the estimated figures released at the C7 launch was 450 HP / 450 LB-FT, so the final numbers are a nice little bump from the original 'estimates.'
