[QUOTE="Saltydawg, post: 341913, member: 2944"] Inline engines tend to produce more torque than a V configuration because of geometry and to a lesser extent the manner in which air flows when it fills/leaves your cylinders. They are generally built with smaller diameter bores and longer strokes because of "packaging". A longer stroke is the same as using a longer lever to move something, you get more torque but you lose some "speed", or in this case the engine revs at a lower limit. An inline 6 cylinder also has 7 main bearings vs 5 main bearings in a v-8, which leads to more stability and support for your crankshaft. Each connecting rod has it's own crankshaft journal to ride on instead of having to share it with another cylinder. This allows a wider base and wider rod bearing for each connecting rod which again increases stability of the bottom end of the motor. Airflow is also important to torque which is more complicated than can be explained on a messageboard. Wide bore cylinders such as found on smaller v-8's running at higher rpm's fill better with large diamter valves and short intake/exhaust runner lengths. Small bore cylinders running at low rpm like longer intake/exhaust runner length cause it means the air is moving at a higher velocity so it carries more inertia. This helps fill long and deep cylinders. Anyhow it's with good reason that most large industrial engines found in semis and work environments are of the inline design. Tractors, Semis, large deisel ships, power plants all run inline engines. It's a stable and durable design. If you wanna race though you're better off designing a v configuration engine to take advantage of higher rpm's that are generally not reachable with inline motors. [/QUOTE]
