Both Nelson performace or Texas speed and performance can get you a cam kit of your choice or grind you a custom cam. they both offer the pushrods and springs of your choice. I am unsure of what gears you have. Be sure to throw a good locker in while you have it apart. Save alot of money and headache down the road. I would guess 3:73s. Check you glove compartment. it will give you a code to tell you what you have. Forget the TB spacer unless is a nitrous plate. Get a tune from NP. dont waste your money on a handheld. Flowmaster is restrictive. Go magnaflow they flow much better.
