Pretty sure, even though the later years used LS6 intakes, it is still a mechanical throttle body on all LS1's...

Actually, the cam is different on some years. I think the '01-'02s have the bigger cam. Not sure if you can swap them or not.

I stand corrected, I do recall that. I think its the 98's with the different throttle blade cam for a faster opening.

1998-1999 LS1 cars had a smaller throttle body cam, which caused the throttle to open to WOT (wide open throttle) faster than 2000+ cars. From LS1.com sticky http://www.ls1.com/forums/showthread.php?t=27514

the housings and blades are the same, but the 98-99 have the smaller cable cam and the 00+ have the larger cable cam.
