Where does the water go?

with right at 300 miles on the 445 stroker I have added more than 4 gallons to the coolant, up to a gallon with each short drive. There is no coolant in the oil so it must be going out the exhaust and yet I do not have a vapor trail behind me. The car runs 190 degrees while driving down the road at highway speeds but will climb to around 210 in traffic. There does seem to be a slight miss at low RPM which may or may not be caused by the one cylinder running cooler than all the others but there is no evidence on the plugs which cylinder it may be and the miss does go away with higher RPM's. I have pressure tested it cold with only a 3 pound drop in 3 hours and I have tested it hot and still not found a leak. There ia an overflow tank which is dry. Any ideas what to look for next?
