The first thing to check would be the tires IMO, say, see if the swaying behavior changes when they're swapped side to side. If yes, then there's the answer, if not, then it's something else.
A stock ZL1 is not supposed to have this problem, let's not act like he needs a ton of aftermarket assistance just for the car to stay stable at WOT.

I'm not trying to argue this point, but I was only addressing the sway-part.
I will say that I don't have any trace of wheelhop or anything like that, too. AND - I have aftermarket sway bars (because of, incorrectly, trying to help with something else) but those didn't help the sway, either.
If you have much road crown, I'm not sure there's much that can be done, OP. I'm not sure it's too reasonable to expect to compensate for that without effecting something else. I wouldn't purport that's your issue, but I'm fairly positive that's not helping.
To arpad's point - even though ZL1 toe links are spherical (if I recall correctly - I replaced mine almost 5-years ago now), they're a little flimsy stampings, too. Before throwing the catalog at it, if tires and verifying the alignment doesn't help, these relatively inexpensive arms might be helpful. There ARE rubber bushings in the knuckles, too (not all if I recall, but of the several per side, I think ZL1s have rubber ones), which could have worn out. I'm not sure how likely, but all of these rubber bushings are under tension when the car is on the wheels on the ground, so it's not impossible for them to wear-out or tear over time. Maybe get a look ALL of the bushings on all of the arms, too.
