Something is not right here. Through an automatic this thing would have to be making around 550+ fwhp to put down those kind of numbers. That is more than a Z06 puts out through a manual, even though the LS7 has 36 more cubic inches and a 7k redline. This car should be trapping 116+ if those numbers are true.

to Inside line for taking a dyno graph they did a year ago and laying them on top of each other.
