I'm pretty sure they are the same. 4.8/5.3/6.0 and LS1's all use the same stock throttle body. The difference is if they're cable or drive by wire. I think the bore is 75mm.

I put an LS1 in my truck and used the truck intake and throttle body, I measured the LS1 unit and it was the same size as the truck so I saw no need to swap throttle bodies.
