1200 HP Camaro ZL1 RESURRECTION by Hennessey Performance. This upgraded Chevrolet Camaro ZL1 is the ultra-rare successor to Hennessey’s infamous 1000 HP EXORCIST upgrade, delivering an overwhelming driving experience and a brutal symphony of thunder and roars. This ultimate ZL1 was built specially for Corey and Krystal Howard, intended to become the rowdiest member of their already-impressive lineup of Hennessey-upgraded vehicles!
