Corvette Conan ZR-12
The C4 chassis was state-of-the-art when it was introduced in the mid-’80s. During its production, Chevrolet knew that it could handle much more power than stock. To test exactly how much power the C4 chassis could withstand, the Corvette team built the Conan ZR-12 prototype (via LSX Magazine).
This custom Corvette had a frame that was five inches longer than stock and an enormous V12 engine under the hood. The engine delivered 700 HP and an insane 750 lb.-ft of torque. Yet even with that kind of power under the hood, the C4 chassis proved to be a perfect match.
