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!

just curious, if the 05 SSRs have LS2 motors, then does that mean that aftermarket engine upgrades such as heads and cams for the C6 will fit on the 05 SSRs too?
