Difficult to tell from your photo, but the engine number is at the front of the block on a boss by the #2 cylinder, ie. on the right of the block looking forward. I hope this leads you to it. There will be ten digitsl: the first two are the year of manufacture, the second two are the model of the car it was originally fitted to, and then a six digit serial number.
