As for the cam, I have the cam card and I believe the duration is .050, but I will post it later and tell you what it says. The headers I have no info on yet since I am not buying them till later depending on how much money I have when I am ready to build the motor, and the rear end is stock posi right now at 2.80 I believe but I would like something around 3.50 ratio since the car weighs around 5,200lbs. I will get back to you on the cam once I pull the card out of the box.
