Bought this a while back for my C5Z06, but with the new build went with a larger throttle body to go alone with the new engine.
It worked great with my LS6 motor with very crisp throttle response. I actually replaced my Shaer ported and poliched throttle body with this one, and this Callaway unit felt just as good with throttle response.
Someone on another forum asked me about the size of the opening on this throttle body. I just measured at the back and come up with an opening of 77.75mm.
I couldn't find much about this throttle body, since Callaway apparently doesn't make them anymore. I thought when I bought it I read that this unit works on all C5s from 1997 thru 2004.
I also could not find anything as to whether they made more than one model with a larger or smaller opening, so I'm guessing it was just this one model but with various anodized colors offered.
So that's pretty much all I know about it. If anyone has any further questions that could be answered from a photo at a particular angle, please let me know.
All in all, if you are thinking about a blue colored throttle body for your C5, it might be a long while before you see something like this available again.
