To me it might suggest that the replacement for the 194 was a 230.
Great minds think alike - I came to the same conclusion. But my Corvair Chevy II parts master from 1 year earlier references the same casting number:
And as I discussed above - this doesn't jibe with the main line production engines being cast in the fall of '61.
And why two different catalog numbers if they are in fact the same part? The dip stick position cannot be the only difference. Besides the 230 was not offered in the Chevy II until 64.
The paper trail doesn't add up.
