The Ultimate Beast! |
| When our GM Performance Parts engineers sat down and designed the ZZ572/720R, we told them to build something nasty. We think they accomplished that mission with a resound 720 horsepower and 685 lb.-ft. of torque--creating at the same time the most powerful big-block crate engine ever offered by GM Performance Parts. |
