Sounds like the engine will work OK. Doesn't seem to be a high performance cam. Make sure that it is the correct rotation. I had a 30' Chris Craft. One engine turned clockwise and the other counter clockwise. Basically, the engine is the same. the only difference is going to be the oil pan, possibly the water pump and rotation. Check for them all.
What is the price of his engine? Also, check with Auto Zone for a crate engine. They are usually fairly reasonable.
