New LS1 Owners - Newbie Tech - 2002 F-Body Throttle Body

What is the size of the stock throttle body on an 02 f-body car?
Is it worth replacing for a 85mm throttle body from professional products? http://www.lmperformance.com/16420/1.html
Also, will the smooth bellows from SLP fit an 85mm throttle body?

Dont bother with that until you go heads/cam, unless you are trying to get max power out of bolt-ons. A popular thing to do when going heads/cam is adding a 92mm or larger TB, so the 85 really isnt worth in many cases.

The plenum orifice is still 75mm so you will not gain much.
I am using the stock bellows on my ProProducts 85mm
setup. The outside diameter is roughly the same as stock.
I think you'd be better off, and money ahead, using a
Baker hose. Which you can order in about any combo of
inlet and outlet diameters you like.

Your better off having yours Ported & Polished w/ the Bump stop ground back for $75.
