On the other hand, most domestic V8's go with a mix of a good bore and a good stroke to get an ideal combination of power and torque. The downside being, you cant exactly spin it up to a crazy-high redline. Again, probably due to just the sheer mass of internal parts flying around at amazing speeds and the risk of valves floating into the piston heads. A common mod for many F-body guys who want a high-revving motor is to actually de-stroke it. Less cubes overall, but the higher redline can be worth it... Most diesels in trucks are inline 6's with a medium size bore, but huge stroke. Low-*** redline, but man the torque is ricockulous. By the way, worthy of note - once you're up to speed and in your ideal RPM range making peak power, your torque does not mean nearly as much as it does, say, off the line on a launch. So, put two theoretical cars with the same exact size/weight/aerodynamics with 2 drastically different motors that, somehow, magically make the same exact horsepower against each other. Lets say one has a low-revving, 330 HP/330 Torque V8. The other is a higher revving 330 HP/250 torque V6 (boy, I wonder what motors Im comparing here...). Assuming both are driving near each other on a course and its...say, like NASCAR where they are running at their peak power most of the time...they should theoretically be able to compete with each other just fine. Now, of course, this all goes out the window as soon as corners, braking zones, and the need for a lot of shifting happens. But, of course, this is why no two cars are the same, right? ****, this isnt a typical MightyBobo post.................douchebags. There, I feel better.
