Does anyone know the differences in the 04 SSR LS1 compared to the 04 GTO LS1? I know the SSR is about 290hp, 5.3L and the GTO is rated at 350hp, 5.7L.

So what is the difference? Cam, throttle body, compression/pistons. Were the heck is that 60 horse difference coming from!

Thanks demonspeed, it helps to have a clear view. I'm not as up on the engines as I was as a teenager.
