use the 4.8 harness on the ls2. you will need to lengthened or buy the extension harness for the cam sensor, you will need to rewire your knock sensor harness to reach the sensors on the side of the motor or buy that conversion part. you will need to tap the block for the GenIII knock sensors

it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
trg-002 lingenelter conversion box, If you want to part ways with the heads on that 4.8 let me know!
I do NOT really want to part the 4.8 out but I am looking to sell it outright.Originally Posted by blacstar
It is a good running motor and I have the Dyno results from it just before pulling it out.
It is complete as pulled from my 2004 Regency Conversion truck but I will have to use the pan and exhaust manifolds as the ones form the 05 GTO LS2 are different...
When you pull the GTO oil pan also pull the windage tray and pump pickup, put them all on eBay prepare yourself to be pleasantly surprised. The GTO front sump pan makes a great conversion pan for import car LS swaps.
Thanx for the info. I feel a little better about the swap now.
I was getting kinda nervous about all of the differences and what all I had been told about such an "easy swap"
