Robert and Elizabeth Posted February 14, 2007 Share Posted February 14, 2007 Ok, for Valentines Day, Robert and I decided to give each other the ultimate gift. We will upgrade the Z just a little more (understatement). We are having Mike at AZPS install a large CAM and headers the last week of Feb. That should put the Z at around 530-550 HP at the wheels and about 625HP at the engine. :D We will post the dyno results after it is done.Mike/Nic told us the LS7 pistons were a little weak for NOS, so we decided to go this route instead. We are not complaining! Link to comment Share on other sites More sharing options...
