I just bolted the headers on with a rich 11:1afr and 28* of timing and with the intake, and it made 373rwhp/371rwtq on a ~6X* night. Why i think its so low is im guessing a good tune on top of that 373whp would have made roughly 10whp more and put me in the ball park of 385 ish. and after the cam and tune it made 392whp The power and torque under the curve are higher, but i still figured i would see 400whp from it.
