Ford Vans 1961-1988 Repair Guides



The engine identification tag identifies the cubic inch displacement of the engine, the model year, the year and month in which the engine was built, where it was built and the change level number. The change level is usually the number one (1), unless there are parts on the engine that will not be completely interchangeable and will require minor modification.

The engine identification tag is located under the ignition coil attaching bolt on all engines except the 6.9L and 7.3L diesels. The diesel engine I.D. number is stamped on the front of the block in front of the left cylinder head.
