The chassis VIN is not typically stamped on the block. Often, there is a serial number, but no registry to match it up against with foreign cars to actually figure out when/where it came from. Not sure on domestic, last domestic I owned was a suburban shaped like a box.
However, if you search the block carefully there will be information "stamped" in to it. I have no idea on your particular engine, but it's often on the driver's side below the head. Good luck and you will probably need a flash light. I use visual clues myself personally, but that will take a little additional research.
