Someone will chime in on this one. I have seen two GTOs on eBay this summer with an LS3 conversion. But I didn't see anything about replacing the fuel lines or PCM swap. The descriptions on both were pretty vague. Wish I could help you out more.

Yea I've seen some also but just seen them list the basic...ls3 heads...ls3 intake...I think I've seen 2 diff. Intakes..not sure..and I've heard of "off set" rockers...and I think some sensors on the back are diff...I'm just trying to get as much info before I jump in :-)
