Hennessey rings out a 705hp Corvette ZR1

Recently retired John Heinricy got a shot to wring out Henessey's new powertrain, a 705 hp LS9 V8 that lives in a new ZR1 Corvette at the MSR Houston. The result is a pretty nice video, but the real news is that this is the exact powertrain that will occupy the engine bay of a certain Hennessey HPE700 Camaro, a car that was revealed back in January.
