I have my 392 ordered, how much power will it make?

And it's going into a truck, and I think I mentioned earlier that the dimensions on the exhaust weren't decided yet, but now they are. I have decided for 3" with x-pipe and magnaflow mufflers. A couple of headers and some head porting will come along when the cash is available. A 750 might be a later upgrade depending on how the car behaves but for now the 650VacSec is whats going on first hand.
