There's no way a Z will get the jump on a GN out of the hole, they can cut 1.9-1.7 0-60ft times while we'll be lucky if we can cut a 2.1. Most of the mild modded ones i see at the track run mid to low 12s, but usually under 110mph trapspeeds. Its all in the launch with them. I remember reading a Motortrend mag, it mentioned that they were speed limited to 120mph cuz they became huge bricks in the aerodynamics department which also made them unsafe.
