I pulley'd my blower kit and got some lower compression stage 3 heads. Car made 548RWHP Corrected @ 5900RPMS We let off a little early because it was a cold night and making over 560rwhp @6k and 500rwtq uncorrected. I like to see the uncorrected so I don't blow up my motor. Car pulls so hard and with the stock cam I bet I can still get 30mpg on the freeway.
