Replacing ‘67 273 with a ‘78 318 questions

Boba; There is a lot of confusion about Mopar torque converters. I'm not sure about Magnums, but all 318's and all 273's are neutral balance, cast or forged crank. --------- All 360's and cast crank 340's are externally balanced. The weighted flexplate mentioned above is for mounting a 318/273 [neutral] converter to a 360 engine.
