Is there an easy way to tell if your engine is ceased up?

So, I have this 1984 Dodge Rampage manual transmission trucklet. I found it abandoned across the street from my house, and my life long dream has been to fix it up (forgotten cars need love too). I’m trying to get it running right now, but before I do too much work, I want to find out if the engine is ceased up first. Is there any way I can do that without taking the block apart?
