2012 zl427?
 

What does anyone know about the 2012 ZL427? I saw one for sale and did a little research and couldn't find much on what came factory or was it dealer installed stuff. Saw an older ad one for sale that said 1 or 7 built. Where an I find actual facts about these cars?

If it's this, is an SLP package and the 427 rating is at the crank, it's not a 427 cubic inch engine:

I hope that is not fwhp as stock they were rated @ 426 ��

The ZL427 was based on the automatic/L99 SS cars. The 6 speed/LS3 cars were ZL454. The L99 was 400hp stock and imo, was a dog. I'll always remember being supremely disappointed at how slow the 2010 automatic SS felt.
