This is my situation. I have a complete pullout of an LH6 from a 2006 Rainier. I've got the motor, all accessories, harness, manifolds, O2s, ECM, BCM, pedal, everything intake to pan. This is going in my Cutlass I am in the process of restoring.

That's all fine and dandy, but now I found that I may be able to get an LS2 out of a 2006 TBSS. The motor is being replaced because "it blew up" or "I think a head blew". I'm hoping the lower end is good, because I have a set of the 243s on the LH6 as a well as another set if it should need them. It's going to be a week or two before I can check it out.

My question is, can I use the LS2 with the ECM and harness I have? Do they use the same computer? Obviously, if this motor can be saved I'd rather have an aluminum 6 liter than a 5.3.

just reprogram the PCM/BCM with a 6.0 file from a car.
look at a GTO PCM/BCM file in HPT to over write with.

Or just copy over the different tables instead of spending $200 on credits.

This way you only have to spend $100.

Thanks for the info. I was hoping it would be pretty simple.
