I have a friend thats buying a 408 and is selling his stock short block from his 08 G8GT, if I'm not mistaken that is a L76. What type of power could be achieved with a L76? I know the dispacement is the same as a LS2, is the part for part power potential the same also?

 

They have AFM, and cant safely handle a cam swap without an AFM delete. Other than that its basically just an aluminum 6.0L with L92 heads.
