Which way is it running, horizontal or vertical?
How long is it? Is it directly behind the carb?
Critical areas internal to the block about midway betweel the oil pan gasket surface and the head gasket surface are the O-ring grooves that seal the bottoms of the sleeves. These O-rings seal oil from getting in the coolant and coolant from getting in the oil. This crack if in the right place could pass thru an o-ring groove and then you may have a problem. It may not pass thru either, depending on where it is. It may or may not be a problem but I would evaluate it closely before I bought it. Casting cracks can grow over time, but they may not grow either. They can have a mind of their own. You can get a better idea of it's location relative to the o-ring grooves if you have access to a used block or if you can get a look at scaled section drawings showing the front and side sections of the engine assembly. If it is a short horizontal crack and above the o-ring grooves it may not be a problem other than keeping JB weld in place. Check the oil and coolant closely for coolant in oil or opposite.
You will likely want to drain the systems to check. Oil floats on water so any coolant in the oil would be at the bottom of the pan. You could pressurize the radiator slightly as another test to see if coolant is transfering to the oil.
