The Cadillac 8.2L V8 made 375 hp and 525 ftlbs of torque when it debuted in 1968. It was all the emission restrictions that reduced power to 180 hp. It wasn’t designed to be inefficient. It’s like having restrictor plates on racecar engines to limit power. The engine can make more power, but the class rules state it can only have a certain amount of power.
