Note that the Rootes assigned engine information isn’t stamped or cast anywhere on the block/heads. So you need to check the assembly date on a small flat by the distributor. It should be sometime before the car build date. For example my car was late December 64 build and the engines build date was mid October, so about 2 months before. All the Rootes tags show is if original valve covers were swapped if the engine was replaced.
