CAT Gear Drives

Boy did this discussion get convoluted. 3 yrs. ago I switched a 440 from chain drive to gear drive and saw "NO" difference in driveability or 1/4 mile time or speed. The only difference was the consumption of Aspirin for the headache the wineing was causing. The other thing is that there is a "non-political" reason to be wary of Chinese steel and that is some of the steel arriving in North America (that's Canada and USA) has a high degree of porisity caused by sulphur inclutions. This is because the Coal they use to make their Steel contains a higher than recommended percentage of Sulphur. That is why some Chinese steel products, such as pipe, is banned for use in North America and parts of Europe.
