Obviously this misses the point of the Z/28 but I guess the appeal is from a collector standpoint, really. A heads/cam upgrade to the LS7 is what the Z/28 really wants, and I happen to know that 550rwhp is possible all natural. Awesome. And when I say possible I mean totally legit to drive on the street.
