Where can I find the engine block serial number at? Curious to see if it's the original block. thanks

Take your starter off, and the number will be stamped on the block behind the starter.

I've been looking for that some time as well ( I needed it to register the car in Poland). In addition to the part serial number under the starter (thanks Soaring!!), you've got a stamped serial number on engine's block. This one was really hard to find, it's on the top of the block, on the surface where the intake manifold is bolted on, very close to the firewall (you have to lean hard on the engine). It's for V8 of course. Last six digits of the number should match your vin.
