Most HO motors produced between 87-93 were RATED at 275-300 torque. Remember, this is just a rating, it is not an accurate measurement of torque. 86- and earlier were rated at 245-260 I believe. For instance, the 2005-08 Mustang GT is rated at 300 horsepower. You put it on the dyno, it would probably only put out 270-75 horsepower. The 300 hp rating was a selling point. Some cars are over-rated while some are under-rated. It's a hit and miss on the actual numbers when a person buys a new car.
