The block casting is a '53-'54 248. The head casting should be 2194819, Normally the displacement of the engine would be the first 3 digits of the engine number. However this doesn't always hold true because it was common to change the engine number to match the title because many states titled vehicles by engine number until the mid 50's. There is nothing wrong with a 248 and this one has the later flat pistons and small combustion chamber head. However parts unique to the 248 such as pistons are getting hard to find.
