Just goes to show you should never put anything in writing that you can't back up. But I'll try. Actually what I was loosly referring to is torque versus horsepower. Compression ratio is just one factor out of a bunch of factors that matter. Lower compression ratios are associated with engine built to make lots of low end torque, but there are exceptions. High compression is normally associated with engines that make a lot of horsepower at high revs. Other factors include size of the carburator (smaller typically helps low end torque while bigger makes more HP at high revs.) The engine bore versus stroke, camshaft, valve sizes, etc all come into play. I probably made a statement that was somewhat misleading since compression ratio is just one factor in many that help to build an engine that produces more torque at low RPM versus an engine built to make more horsepower at higher RPMs. And there are plenty of exceptions and other combinations that work just as well. Engineers, hot rodders, tractor pullers, and a few others may disagree, but this is my explaination...BB
