Sorry to hear about your motor loss, that stinks! I'd say take it back to the builder for the rebuild and at the same time get the crate motor your talking about and drop it in. After the rebuild on the old motor you can sell it.
Chances are the builder will not rebuild the motor for various lame reasons like he didn't install the valve covers or water pump or something. But it's worth a shot at getting him to make it right.
Great advise here. It wouldn't matter how long he spent and you could get some money back. Something is better than nothing.
