i think you can port it to 80mm, and i also heard of some company being able to mate a 90mm ls2 opening on a ls6 intake so you can run a 90mm throttle body... I guess its not far off a fast 90. but i couldnt tell ya who does it.

I measured my LS6 with calipers and it is 75mm, using a 78mm fast TB you can feel the lip. Not a lot of plastic in between the seal o-ring and the ID don't think I would try to port unless you know what your doing,
