I don't know the actual rating on it, but probably the car I've had with the most juice was a 1967 Mustang that a previous owner had stuck a 351 Cleveland engine into; it wasn't the absolute most powerful engine on the planet, but it sure did get the job done, and did it well. At that time my best friend had a 1967 Cougar, so our cars made a nice pair. It was cool how the interiors of them were virtually identical, other than one saying "Ford" and the other "Mercury," while the bodies were so different. Ahhh, memories...
