600+ is getting a little ambitious. If the LLT makes 2.6% more power in the Camaro than it does in the CTS, then that should translate into roughly the same sort of gain in the ZL1. There is also the electric power steering, which would free up a bit of power in the ZL1 vs CTS-V (I think ... unless the CTS-V has EPS too ... ). So all in all, 575 hp isn't unreasonable to expect for a ZL1. Thats obviously not 600+, but its a good deal above 556 too ...
As far as being being 'astounded' by the numbers ... for me, that would take a sub 4 second 0-60 and a 1/4 in the 11's ...
I think those numbers are doable, given what the CTS-V accomplishes but I'd still be astounded to see them
