Ken,
You are going to have to sell me on the block universe (again) next weekend when we tape the inaugural episode of Quantum Conversations. I can buy retrocausality on the micro level so I do not think the two ideas are necessarily connected. I think the block universe is merely a way to make retrocausality seem palatable on the macro level, or, rather, to make better sense of the quantum-classical contrast. But it assumes that space and time have some ontological status beyond mere relations.
Ian
