8 cylinder motor serial number location

I have an 8 cylinder block I would like to id. I can't seem to find a serial number on it, only the casting numbers.
Where are the serial numbers located on these?
The casting numbers --
K88
300000
CWC

  • 30000  =  1948-1950.   Date codes should verify this date.

  • Casting date of Nov. 8, 1938 or 1948. So in a 1939 or 1949 car... Is it a rectangle pan, or a wide pan at the rear? That will tell you if it's 39 or 49.
  • Two pictures, no oil pan, head or crankshaft
  • Cast in 48 for a 49 model year car.
  • Kerry, I will take a photo of mine tomorrow where the number is.  It is in the front on the machined pad on the top near the exhaust manifold.
  • Between the first two exhaust outlets. 
  • Deck surface, right front corner.
  • Here you go. Numbers were a little rusty but I think you can see where they are.

  • Thanks guys, yes this is a different location than the 6cyl.
    49 418752 serial number
