It seems that your code is missing one character, as it should have letter for the plant code (F is usually Flint) then a Month/Day code, and lastly, the application code. You might check for a casting date somewhere on the block or head. I can't really give you an exact location on that generation of Chevrolet 6, as my knowledge is more with the earlier 216/235/261, but you might look somewhere near the starter.
