Hey im not real sure what kinda durations i need on my cams can someone give me a good idea its for a 4.6 gt and i wanna see what kinda power that gives.
One thing you should do is match your rear end gears to the new cam's power range to get the max performance. The stock 3.27's will probably kill the new cam's power range. Unless you do the install, cams are not a good bang for the buck on 4.6's. You would be better off with gears and/or blower.
