Not trusting HF, I went to Lowes for mine. I rebuilt my rear and wanted to measure the heat rise. At 80 ambient, it was only 110 after climbing a long hill. These can be used to figure out the timing also. I was not advancing the timing enough and getting over 200 after climbing the same hill. It was over200 at the top of the radiator and about 170 at the bottom. I don't know what the heat rise should be, but it normally runs about 180.
