I have a 216 engine (don't know what its from) that has some unusual marking on the side of the block. Casted on the side is the number 48 in the center of a circle. The casting is lifted and is about he size of a half dollar? Has anyone seen one of these before and if so what is it?
I own several pre-war 216's but the "48" marking is very unique and interesting.
