460-560, seems I read here somewhere the 560's were a "5" plow tractor, thought it was a stretch but the neighbor's 460 with 3-16's plowed faster then our Super M with 3-14's . The discussion about narrow torque bands makes sense. I have had some experience with Ford Fusions with the 4 cylinder and 5 or 6 speed auto transmissions, when you come off a light hard it's interesting to watch the transmission keep the engine RPMS up (in the sweet spot). The comment about automotive engines not being rated to run wide open is right on. Tractor engines are more like general aviation aircraft engines, they produce maximum torque at lower RPMs. You have to keep the prop speed below the speed of sound so you can't run the engine faster unless you add reduction, thus adding weight and complexity while reducing reliability. Most automotive engines don't convert well even if you put a reduction unit on it because they don't like running at the higher rpms needed to make maximum power.
