Dave,
I'm not in front of my books right now but that would probably be a 4th generation 218 cubic inch MoPar replacement engine. Each time the parts got upgraded the MODEL number went up one digit, not the displacement. For example when the oil pumps changed from the gear type to the geroter type the model number changed. This model 221 should be a 218 engine.
