I'm wondering how an LS4 wwith a factory rating of 303 HP in an Impala would compare to the GMC turbo charger v6. Impala shows a 3711# shipping weight or 12.25 # per hp. Don't see how u ccould get to the 11.00# or around 3350#. Maybe Chevy has a secret superceded body to get the weight out. Does anyone know if the LS4 aluminum block motor in the 2006 up Impala is the same 5.3 that was in the SSR?
