Is the ZZ427 available yet?

[CanadianPoncho]

I ran the part number for the ZZ427 at work (GM dealer) the other day and it didn't show up on the computer. I'm in Canada and wonder if the motor is out in the U.S. It's PN19166393. If it is out in the U.S, is anyone running one?
Here's the info from GM Performance Part's website:
