Take a look at the casting numbers on the block, and use Mortec.com for all your casting number needs. This includes any cylinder head ID questions you may need answered.
More than likely, it'll be a 305. You couldn't get a 350 stock in 82, and sellers like to lie.

 

A quick way to tell is to look at the Harmonic Balancer. A 305 has a short thick one and a 350 has a talller skinny one, at least I think this is right, anyone else know the specifics on this?....

 

Balancers are interchangeable. You can't tell that way.

Like the other post said, the only thing that doesn't lie is the block casting #. You can't make a 305 block into a 350, or vice-versa.

Like the other post said, get your block casting number (behind the driver's side head, on top of the bell housing flange.... clearly the easiest place on the whole car to read a number from) and look it up.
