To build on Brad's answer. Most states used the engine number through '55. A few used the unit serial number which would be on the data plate in Brad's second pic and I just learned from Brad that Utah used both. Over the years many vehicles have had the original engine replaced without re-titling the vehicle. Obviously this creates issues when selling the vehicle and transferring the title. If yours is titled using the engine number, that number will be on a raised boss just behind the distributor.
