Not sure if this is the right place to post but it's the closest I could find. I have a 2005 STS that came with a V6 LY7 and the motor blew up, no one wants to buy it so I figured why not strap an LS in it and have some fun? I'd like to put an LQ9 in with a 4L80E behind it. The problems that I'm seeing are; is the cluster going to work, what do I have to do to get the electronics to work, and is that rear end going to handle that kind of power. This is going to be my first swap so any input will help.

I believe that the STS is like the CTS rear wheel.

It's RWD.

This forum may be close, but there aren't too many STS guys here. I certainly don't know anything about the STS platform. I think you may have some better luck on CadillacForums.com. They'll at least be able to tell you if the computer is compatible. I'm sure someone has attempted this before. I've even seen a video of a 572 in an STS.

I would get in touch with 3d, they have the most amount of history with the sts, and could set you up properly.
