However, the LS2 TB is 90mm, so I imagine the LS3 one would hook right up.
They're probably the same, but I'm not sure.
Edited: BTW, I just checked Gene Culley's site (gmpartshouse.com), and I couldn't find the info on the TB for a 2009, but when I checked for a 2008 it said:
Throttle body, corvette
05-08 $529.59 $529.59 $299.00
Includes Throttle Position Sensor.
So, still not sure, but the above indicates that the same TB is used on the 2005-2008, and I'm sure the 2009 and 2010 LS3 also.

Spoke to Corey from LS2portworks and he said its the same. I installed his ported throttle body on my LS3 and externally it seemed the same and has worked like a charm.
