Hey There<br /><br />It would seem torque is more important in car motors. Here is what I mean. In 1971, Pontiac put out a 455 with 390 hp and 510 ft/lbs of torque at their appropriate rpm. At the same time Chevy put out a 454 with 450/460 hp and 490 ft/lbs of torque at their appropriate rpm. I think a Chevelle with the 454 and a GTO with the 455 were about the same for speed, etc. Would that be about right?<br /><br />Now, was someone playin' with the numbers or what? Can someone 'splain it to me? How would all this relate to boat motors?<br /><br />thank you<br />Billy Bob

Howdy, BB.<br /><br />To keep it simple, Torque is twisting force.<br /><br />Horsepower is force applied over a distance, or work accomplished.<br /><br />As in autos, outboard hp is a mostly marketing tool and torque makes things go.
