I have a few question on this.

I found a 2000 5.3l that came out of a suburban. I have a 2003 Silverado 1500(4.8l) that I will be putting it in. What all do I have to swap from the 4.8 to the 5.3 to make this work. I do know that I will have to swap intakes. But is that it?

I will also be putting a cam in it as wee and have been doing a lot of research. Any links you guys have for the cams you guys have used will be appreciated. Thanks in advance and I do know this has more than likely has came up before but I figured this would be easier.
