Slight cosmetic changes.. you're going to be able to tell the difference between the 2006 and the 2008, but only if you know what to look for.. (to our wives it'll be the same

) I'm interested to see what they do for the redesign though.. I've heard from some sources it's pretty nuts.
Oh and the new motor is in the 630HP range with 8.4L a new intake maniffold covers ten individual throttle bodies and has two intakes.
