I need pointers

So going to look at a 1980, 360 thats for sale locally. Its in the car and they guy wants whoever is buying it to hear it run, before he pulls it. Its in a 73 roadrunner and he says its a fast engine, and has only had the valve covers off. He said he thinks its cammed, but does not have any documentation. He bought it about 4 years ago, and the only reason he is selling is because he found a 340 for his car.

He is keeping the aftermarket intake but including the factory 4 barrel intake and all accessories, even the carb.

It nice that I can hear it run, and I planned on bringing my compression tester with just to verify all the cylinders are good, but Im not sure what a stock 360 should have for cylinder pressure. What else should I look for?
