I have had this experience too often in my early days with my 64 383 wagon and a couple of other cars. I now refuse to hook up the heater core. First I dont drive in the winter anyway and secondly even with replacing I used to lose one every year or so. when i pushed the RPM high. (I figure the heater cores are not up to the strain of a B pump at 6500rpm) Enuf already. Now I dont worry about it.
