I was wondering if anyone has had experience with the 80mm throttle body sold by a place called "Professional Products"?

I am interested in this to use on a '99 Camaro SS with
LS6 intake, heads, cam & headers.

How well did it work for you? Does it have the earlier
LS1 short throttle arm or the longer later version?
I want the short arm.

Here is the URL to the item:

Any input that you may have would be appreciated.
