Ya got me! I know Holub is planning on getting twin turbos on his, and I thought that is what they were going to call it. It is confirmed that they will be called the "ZL-1 supercar package" on the gmmg window sticker. However, they may or may not be badged on the fenders. Also the stage 2 includes headers, new cam, different reworked LS-6 heads, ported throttle body, dyno sheets, etc. Rated horse is 475 HP. Mine is going to be silver. I am getting it from Lujack Chevy which is 1/2 mile from my home. They are excited about the car as well. They are talking about having a small party upon delivery. It is great to see such enthusiasm around these cars. They may not replace the muscle cars of the sixties or seventies, but I bet the same was said about those cars in their day. Can't wait!!
