Request for Torque curves on stock crate LS2 and LS3

can somebody post either dyno graphs or the actual torque numbers for an unmodified LS2 and LS3, from 3000 rpm on up?

I'd like to compare the curves between the two, see how much better the LS3 is or isn't over the LS2. I'm looking for an apples to apples comparison. Ideally, I'd like to see engine dyno charts of the LS2 and LS3, but a chasis dyno would be ok too.

I've web searched but get too many dyno graphs of modified engines, nothing i can make an apples to apples comparison with.
