Hi i'm new to the forum i searched an didn't come up with much on this and i need some help/advice. I have a 2000 z71 with a 5.3. I'm doing a rebuild an making some changes. I already have a comp thumper cam, .30 over hyper. pistons, Lt headers, and I was wondering if i could buy the flex fuel, injectors, rails, tb, an intake manifold off a 2011 5.3 on my 2000? And how much I would benefit from it.

Thanks Brandon
