Help! Throttle body question.

I have a stock T/B off of an 01 GMC 4.8 that i'm trying to get rid of. I cleaned it and ported it. Does anyone know what size this thing is? Part number? I just want to know if it is LS1 compatible or not. Tried getting some answers from the truck site but they haven't been much help. Thanks for any info you can provide.

Ok, thanks. I was thinking that I wouldn't get an answer.

That will interchange the closest with the 98-99 f-bodies as it has the same cable cam as those. 00-02 f-body cams are different. The coolant tubes on the bottom and the fresh air tube on the top are slightly different than on all the f-body T/Bs. They are all 75mm.
