However, the "size" of a motor can refer to different things. Here's a breakdown:
* Displacement: This is the volume of the engine cylinders, measured in liters. The Ford 7.3L engine has a displacement of 6.9L (approximately 420 cubic inches).
* Horsepower: This is a measure of power output. The Ford 7.3L engine produced different horsepower ratings depending on the year and application, ranging from 185 to 235 horsepower.
* Torque: This is a measure of rotational force. The Ford 7.3L engine had high torque output, typically around 440-500 lb-ft.
So, while the "size" of the Ford 7.3L diesel engine is 6.9L in displacement, its horsepower and torque output can vary depending on the specific model and year.
