I Know this is not a popular choice, but money is tight right now and I need a new torque converter. They offer one with a 400 RPM lower stall speed, and they call it heavy duty. Will this thing hold up to a little extra power, or is it a complete piece of junk? I can get one pretty cheap through a friend, but don't want to waste the time or money if someone else has already tried a PDQ and been completely unsatisfied. Is it even as good as a stocker? Does the 400 RPM lower stall speed help or hinder performance?
