Help deciphering a 1969 Corvette block number please???

It doesn't look like like that block is original to your car. You can check out VIN # and Identification numbers at the Corvette Action Center: http://www.corvetteactioncenter.com/specs/c3/1969/69id.html

Hi Robert, the last six numbers of the VIN and the last six numbers stamped on the engine block match, so it is the original engine. I just don't know which one.....

The last 6 numbers would indicate the car was built before the end of September, 1968. There should be 7 digits in front, starting with 39: 3932386, 3932388, 3935439, 3946052, 3955270, 3963512, 3956618 for various combinations of 350 / 427 ci engines and horsepower ratings. The '2195' doesn't make sense. Maybe it was a replacement crate engine that was then stamped with the build number from the VIN to make it look like the original engine.
