did i crack my block

[69chevytrucker]

long story short built a 350 put water in the rad to test it got busy forgot water in it . i moved it in the spring and found a frost plug on the ground. i put a new plug in. just getting it ready now drained the oil engine only had about 30 kms on the build just one test run. no water in the oil or filter so i put new oil and filter i just started filling the rad with water for the first time since the new frost plug was put in a year later. water started pouring out the water pump weep hole and some drips out the block heater. i stopped and now im going to wait till tomorrow to see if i have water in the oil . what are the odds i cracked my block
