Well I have seen dynos from 280 all the way to 320 rwhp stock...dynos are all over the place.

I have seen some dynos of the GT and they are usually 260-280.

It adds up when you think of the LS1 being at ~350hp (as its rating was in the vette blah blah blah) and the GT right around 315...it might have been under rated slightly.
