Barn find 1940 Chevy Sedan, showing 63K original miles. 216 engine in place and appears to be in fine shape. However, the only #'s I could read on the engine were as you'd expect, on the pad behind the distributor: 3493I60

Don't appear to be original #'s, or at least anything I can match up, but curious to see if anyone else has any definitive information.

Would make the find a bit more exciting to know it was likely an original block???

Thanks in advance for the help.
