Can you make out the stamped Type and Serial no. on the engine block? It's supposed to be on the left side of the block, just behind and slightly to the rear of the distributor. So if you stand at the left headlight and look past and to the right (in terms of your line of sight) of the distributor, you'll see a 4-inch long, 1/2 inch high, flat area on the side of the engine block. Clean it up and you should faintly see the engine type. Tire chalk may help accentuate the lettering. From this perspective, it's partly blocked by the distributor, so you'll have to do some twisting around.
