Default 05-up block internals differerent than 99-04

I was wondering if the block,crank, rods and pistons are different in the 05-up GT's than the 99-04 GT's?Also how much power can the 05-up stock bottom endhandle?

general rule to follow.....some people get more though......the real answer is as much as it can before going boom....you wont be able to pinpoint it down really

so the internals must be the same because thats about where the limit is on the 99-04. Is the rods still the weak point.
