Check the exhaust ports on the heads. If they look like this with the two middle exhaust ports together, it's a small block....

If they look like this, with the ports spaced evenly apart along the head, it's a big block....or a small block Ford!!!!!

The 400 small block is a very desireable motor to start with. They can be built as a docile street motor or a fire-belching drag strip motor or anywhere in between. It's no big deal to make 500 hp and 500 ft/lbs of torque with one if you get up off the dime and buy the correct parts. And you can make 400/400 on a budget if you are short the sheckels to do it right.

Just depends on what vehicle the motor will go into and what you want the vehicle to do for you when it's finished.
