Default Identifying my engine

I was told when I bought my car that the engine was not the original, but the seller didn't have many specifics on what the current engine was from. It's definitely got the same TPI manifold and valve covers as a stock motor, but I have no idea what sort of longblock may be in there other than that it's some kind of Gen I 350. What casting numbers should I look for to figure out what I've got in it?

You will find the numbers for the block on the right side of the engine at the front just below where the heads meet. Their stamped on a little extension off the block.

The auto transmission numbers are cast on the right rear of the pan mounting flange.

It would REALLY help if you fill out your profile. At least regarding the car.
