I got a ls1 drop out that no one wants to buy at a reasonable price and I lost intrest in my swap project. So can I use the front accessories as I have them so I can use the ls6 intake and not worry about the water pump. I want to use the ls1 injectors and the fuel rails. The big thing I am iffy about is the ECM. I will add some other mods so will I be able to use the 05 ECM and wiring? I know the injector plugs will need to be switched and sensors switched. Is there anything else I need to look into? Ls1 is from a 02 fbody and truck is a 05 ecsb. The 4.8 is at 150k and I love it but I need more. The ls1 has 30k on it and it needs a home.

 

are you selling it or swapping it....?

 

if your gonna go that far into it as in changing intakes and accesories i would just say pull the 4.8 and drop the ls1 in. Its not ahole lot of work everything will bolt in place as the 4.8.. Then you more hp and lost 80lbs..

But if im not mistaken if you change over to the fbody accesorie drives you will have to reroute the altanator wire.. Not 100% sure but i think so.
