I think I have read through the entire thread but I am still a little unsure on exactly what it takes to make this swap happen. Basically the main hangup is the cam sensor correct which is what all this custom machining is about, right?

Rob- Im in Central CA also. I have a complete 5.3 with harness and computer which I was going to use on another project but have since changed directions. So Im looking at this LS on the stand and the 440 in my satellite and thinking I can make this injection swap happen. I also have some spare coil packs and LS odds and ends if you need some.

Great thread
