Don't get me wrong I hope it makes 600 hp, me being an LT1 guy and all. But Sneakin, 360-370 at the tires is high. I think more like 320 to the tires given what I have seen that he has. Alex, let us know. And if it makes 370 na at the tires we may need to discuss how much you want to help me install in cam in mine.
