      difference between these 2 torque converters

      Can anyone tell me the difference between these two torque converters? The blue one has a 6 stamped in the housing and GM 4M written on it. The black one has no markings.

      Going into a 67 Lemans with a 455 and th400.



      I know nothing about torque converters even after reading about them. Any suggestions?
