I don't see what grounds you have to say you were ripped off without a sonic check which would prove the block is unusable.

They said it is a standard 428 block that had been recently honed. I don't see what grounds you have to prove otherwise?

Am I missing something?

Have you tried the drill bit test? Go into the freeze plug holes and see how large a drill bit you can fit between the cylinders at various places and various bores. You can then do the math and see (approximately) how thick your cylinder walls are. That would be a quick test before spending the money to do a sonic.
