Default 85MM throttle body

Will an 85MM throttle body fit on a 2010 5.7 without enlarging the intake? The stock TB is 80MM but it is my understanding that the intake is larger than 80MM. So, what is the size of the stock intake?

I have a 85mm on my truck but I will tell you right now that I did not notice a difference when I installed mine. But yes a 85mm throttlebody will fit since all they do is port the inside to make it larger.

It would be nice to see some dyno numbers to see if it's worth buying.
