Crank pulley hole alignment question

Not sure when the change was, early offset, later even, my 67 273 has the offset.

My '69 340 pulley has the offset hole. So did the old balancer. My aftermarket harmonic balancer, which is neutral balance for the forged 340 crank, has evenly spaced holes. I don't think you'll find any aftermarket balancers for either cast or forged cranks with the offset hole.
