Yeah I saw that, great number!
I went 154.8mph bone stock back in November before I built the car.
We are putting in a 440ci built LS7 with a twin turbo set-up in a few weeks, should give us some decent power :rockon: 200mph is the goal!
Good luck! Keep a close eye on the front bumper overhang, Hennessey had some issues with high speed testing on theirs - but I've heard it's been fixed by GM since then.
