depends on the year of the z06
I have seen as fast as high 11s bone stock at high teen traps
and then there are crappy drivers in poor air who go high 12s at 112 ish
to hang with a z06, you definitely need good heads cam + something else, be it ALOT of weight reduction, the bottle or some more cubes AKA a stroker
Or you could run boltons and a whole bunch of spray, Or a blower setup putting out 380+ at least on a full weight car
