If I block a contact on ios 7 on my iPhone 5c, can I delete it and have it still be blocked?

No. If you delete the contact, the phone no longer has any information on that number when it calls. When that contact calls now, the phone compares that to the contact list for Caller ID, find the block signal and blocks the call. If you delete the contact, the phone has nothing to reference.
