He also talked about the 5.3 going into teh GP. Engine code number is LS4. He said that the engine package was for GP, Monte and Impalla. He said it was for mid year of 2005.
I doubt that it would be called the ls4.....that would mess up GM's engine naming scheme. my guess would probably be the same as a current 5.3 or something very close to that.
