Guys, just give Jon B @ PartsRack a call. It'll be worth your dime, trust me!
BTW, I did a pre-dyno today and hit 449.4rwhp and 489.0rwtq (corrected). I do have the K&N Filtercharger installed. I'm hoping for (fingers crossed) 470/510 respectively, anything more will be gravy, anything less will mean a 300hp BTR nitrous kit
