LOL!!! Well was one of the 22 but viewed the thread to see if it was a TB cleaning question.  My car is in storage now so I cannot measure mine with my micrometer... And I doubt my old LS1 manifold on the shelf would help any.

Well, I bought a 85mm and I compare them two together and both of are the same size but didn't think the c5 came with 85mm. I'm trying to figure the stock size or I just wasted money 85mm TB that I didn't need in the first place.

75mm, I believe. If you change it, you'll have to retune (specifically the ETC Scaler) to tell the PCM the new size of your TB.
