your tb now is 65mm... more than adequate for a stock motor. if you have a project you're working on or are going to need more air then just find a take off 70mm, that'd be your best bet.

The aftermarket Mac tbody on my GT is only 70mm, my upper intake plenum is ported and polished to 70mm, this on a 4.6L GT, I am not sure what the size of the stock tbody was, probably also 65mm, I one one from it that that is half shafted and polished, don't think it would fit on a V6, but it might, not sure.

Not a bad deal, or you can do your own. I have
posted the text of how-to for that lots of times.
I need a good one here for V6s articles.

basically splitting the shaft of the throttle plate right down the center of its axis so its flat on one side then there is only a shaft on one side of the throttle plate, less resistance to flow like that.

It can have major gains, and the smaller
TB's have shown over ~100 CFM gains
thru doing this process. But they are
more poorly constructed. I'd say
the above 60mm TB goes at least +50 CFM.
