I'd have thought more.
415 RWHP. Temperature 38 C, Humidity 90%...
Obviously not the ZR1 but this is.....
+/- 15% loss from crank to wheels is about right. Then take altitude above sea level and engines, other than supercharged, lose even more.
Normally and almost always the case when you consider the losses to get the power to the ground for true GM more than once underrated power numbers especially when the insurance companies got involved in the early 70's . But now we see the ZR1 making about 98% advertised power at the wheel. Full circle we have come .

I've always heard +/- 12% which would put it at 435HP
What relative effect does elevation have?
According to Google
Naturally aspirated engines are particularly affected, with a loss of about 3% of their horsepower for every 1,000 feet of elevation gained.
