Please tell me:
* What kind of engine is it? (e.g., car engine, motorcycle engine, airplane engine)
* What is the make and model of the engine? (e.g., Ford Mustang 5.0L V8)
* What is the displacement of the engine? (e.g., 350 cubic inches, 5.0 liters)
Once you provide me with this information, I can help you calculate the cubic inch size.
