To hopefully answer your cranking amps question, the 8 volt battery with les cca will not crank as long as the 6V. But it has higher bolts pushing it. However your starter only needs about 100 amps. That said, 6.4 volts is low. You probably have a bad battery. No matter what you put in, it will work better.
