The discussion centers on comparing the capabilities of high RPM gas engines and low RPM diesel engines for moving heavy loads. It highlights that while both engines can produce the same horsepower, the diesel engine's higher torque at lower RPMs allows it to pull significantly heavier loads, such as a 60,000-pound truck. The conversation also touches on the mechanics of gearing and how torque and power relate, emphasizing that high RPM engines typically produce less torque, which limits their ability to maintain power under load. Additionally, the feasibility of using a ship engine's torque to pull a dragster is debated, with the consensus that despite high torque, the dragster's performance is constrained by tire grip and gearing. Ultimately, the discussion illustrates the importance of understanding torque, RPM, and gearing in engine performance, especially in heavy-duty applications.

Thread will stay locked. It is getting too disjointed and rambling to have any value. If there are specific questions, they can be asked in new threads. But please: be specific.
