I am running a Motometer. Where should the red be for normal temp? While I was running my first set if test runs the temp would stop in the middle of the top bubble. Is that too hot? At what point should I be worried?
Steve, that's perfectly fine. Your T will let you know if its unhappy temp wise, by blowing out steam and coolant from the overflow tube.
Yup. If it's blowing steam and coolant it's unhappy. If it's not - everything is fine.
On a side note Steve, Its amazing how timing/fuel mixture can influence the temp your T runs at. You can actually see the difference on your Motometer while driving, and adjust it accordingly.
Gauges vary a little. In the summer in North Alabama mine will read a little below the window/black line. In the fall and winter, maybe a quarter inch from the bottom to half way up to the black line. I am running a new Berg radiator and 160 thermostat (no water pump). After awhile you will learn what is normal for your car. And as other have said, if you don't get her boiling over and steam, you are OK. The purpose of gauges is to notice trends or readings out of what is normal.
