Will any other engine fit or do I have to have a 1933 Master engine (32, 34, 35 etc...)? Was Chevrolet building different style engines each year?

Recently purchased a 1933 Chevy Master 4 door sedan with a bad engine. I also purchased what I thought was a 1933 engine that came out of a coupe to rebuild. Unfortunately the engines are not the same. The one in the car has a casting number 836915, G 19 3. The one on my barn floor has a casting number 473180, B 23 3. ( different size distributor cap, different engine mounts, different water pump configuration...ect.) Can anyone tell me what I have? Are any parts interchangeable between these two engines?
