Your water temp T stat will open pretty fast even on a cold day. I believe the stock T-stat is a 192* and will basically stay closed only until it reaches the set temp. Doesn't take very long. Then of course is will open and close as needed to regulate the water temp.
The oil temp will run higher then the coolant temp.
My LS7 heated up to operating temp in a few minutes.
