Can I delete a blocked contact and still have it be blocked on an iPhone 5c with ios 7?

Sure, any number you block, stays in the blocked number list whether they are in your contacts or not. So you can delete those numbers in your address book that you block and not worry about seeing the number on caller ID again until you either get a new phone or delete the blocked numbers list.
